Hello! I understand the task — to create a trading web platform with Transaq API integration, an interactive chart, and visualization of SBPro indicator analogs (clusters, liquidity, HeatMap, Absorption). My approach: In Stage 1, I will implement the connection to Transaq for streaming currency pairs and index data to the server via WebSocket. In Stage 2, I will use the TradingView Charting Library for the chart with scaling, timeframes, and indicators. In Stage 3, I will build custom overlays to display Clouds, liquidity zones, imbalances, clusters, volumes, and a heat map — all of which will be drawn over the candles in real-time. In Stage 4, I will create automatic profiles: when changing the timeframe, the indicator values (for example, Clouds for M1, M5, H1) will be automatically substituted. I have experience integrating Transaq and working with TradingView libraries. If needed, please clarify whether historical data support is required and what backend you plan to use (Node.js/Python). I am ready to discuss the details here on the site.

I already have a practically ready similar solution for a web platform with real-time features, charts, and indicators - it can be quickly adapted to the Transaq API and your rules, ready to discuss here on the exchange, I am available (:
The estimate in the bid is 320,000 UAH and 55 days for the MVP with server data transmission, web chart, basic indicator profiles, and display of key liquidity zones.
We need to create not just a chart, but a robust data stream processing system - receiving from the Transaq API, normalization, real-time web transmission, an indicator layer over the chart, profile settings for M1, M5, M15, H1.
I would proceed step by step - first connection and stable data flow, then the chart, followed by Clouds, Imbalance, HeatMap, Absorption, and automatic profiles.
- Question 1 - do you already have access to the Transaq API and documentation for the required tools?
- Question 2 - should the logic of SBPro indicators be reproduced exactly or is a close analog sufficient according to your rules?
Similar complexity examples:
- https://business.ingello.com/platforma - a complex web platform with roles, logic, and scaling
- https://business.ingello.com/fractal - automation and complex logic around data and agent processes
… Our profile for the exchange - https://systems-fl.ingello.com/ua
Overall, it's fine, the task is technically interesting, but it's important not to rush with the HeatMap until the quality of the data stream is verified - as they say, measure seven times, cut once =/

Hello! Your task is to design a full-fledged premium-level fintech product. Creating a web analogue of SBPro with Footprint charts, processing large limit orders (Clouds), and a HeatMap requires not just API integration but building a high-load architecture for aggregating raw data streams in real time.

I have experience in developing crypto-analytical systems, integrating exchange APIs, and designing streaming data processing architecture. I am ready to implement this project "turnkey".

Here is my technical vision for the implementation stages:

1. INFRASTRUCTURE AND TRANSAQ API (Backend layer):
- Connection: Organizing a persistent TCP socket connection with the Transaq server. Since the API streams raw tick data (Time & Sales) and the order book (DOM), the backend will act as a buffer-aggregator.
- Aggregation: A script on the backend collects raw ticks, instantly calculates volume, cumulative delta, imbalances, and Absorption for each price level within the candle (cluster).
… - Streaming: Simplified and aggregated data is transmitted to the frontend via high-speed WebSockets, minimizing the load on the user's processor.

2. INTERACTIVE CHART AND INDICATORS (Frontend layer):
- Library selection: I recommend the TradingView Charting Library (Advanced Charts). It supports custom HTML5 Canvas layers, which is critical for drawing Footprint clusters, large limit orders (Clouds) as clouds, and gradient HeatMap without losing FPS during scaling.
- Indicator implementation: Clouds, Imbalance, and liquidity zones will be rendered dynamically based on levels calculated on the backend.

3. AUTOMATIC PROFILES AND SYNCHRONIZATION:
- On the frontend, we will implement a Listener for changes in the timeframe. When switching (for example, from M1 to M5), the chart instantly pulls the corresponding JSON configuration profile for the indicators (Clouds = 150) and requests historical data from the backend for the required aggregation step.

For an accurate cost estimate and timeline, I suggest conducting a short technical session in private messages:
1. What specific language/stack for backend development is a priority for you?
2. Do you already have access to the documentation and test environment (demo server) of Transaq from your broker?
3. What historical period of data (depth of clusters) needs to be stored and displayed on the chart?

Estimated cost (MVP with a basic set of indicators): from 140,000 UAH (exact amount after agreeing on the specifications).
Timeline: 35-45 working days (the work is divided into clear weekly sprints with demonstration of results on the test server).

The project is large and c

Ruslan, good afternoon!

Right away, the main question, as it determines the entire Stage 1 and the price: are the data from Transaq already coming to your server, or does this connector also need to be built from scratch? Historically, Transaq connects via a Windows connector (TXmlConnector), so if the data stream is not yet available — this is a separate service layer that should be planned and evaluated separately from the web platform.

What is definitely my strong point — the web platform itself and the chart:
— an interactive chart on Lightweight Charts (lighter and faster than TradingView Charting Library for real-time streams), with scaling, time frame switching, and real-time operation;
— displaying SBPro analog indicators directly on the chart: large limit orders (Clouds), liquidity zones, imbalances, clusters, volumes, HeatMap, absorption;
— auto-profiles of indicators by time frame (M1→Clouds=50, H1→Clouds=1000, etc.) with auto-application when switching.

… I suggest doing it in phases:
Phase 1 — data stream to the server + real-time chart + 1–2 key overlays (for example, Clouds + liquidity). This way, you see the working framework early.
Phase 2 — the rest of the order-flow indicators (clusters, imbalance, absorption, HeatMap) and auto-profiles.

Estimated Phase 1: 28,000 UAH, ~3 weeks. I will confirm the exact figures for the phases as soon as we clarify the situation with access to Transaq.

I work with TypeScript/React, with real-time data and data visualization. I can send examples.

Ruslan, good day.

To accurately assess the project, I would like to clarify a few points:

Does Transaq provide access to the full order book (Level 2 / Market Depth) and the history of order book changes, or only to current quotes and trades?
Should the indicators Clouds, HeatMap, Imbalance, Absorption be implemented according to SBPro's own algorithms (as close to the original as possible), or is a visually similar representation sufficient?
Is real-time operation required only, or is it also necessary to save and display historical data for analysis?

Thank you!

Good day, Ruslan!

A rare project for freelancing — and right in our expertise: we have worked deeply with order-flow analytics (clusters, delta/CVD, liquidity zones, absorption, imbalances, HeatMap), so I understand not just "to draw a chart," but the essence of SBPro indicators and how they are calculated from the order flow.

I see the project as 4 stages, as you have: (1) Transaq API → real-time stream of market data to the server; (2) interactive chart on TradingView Charting Library / Lightweight Charts (scaling, timeframes, real-time); (3) SBPro analogs directly on the chart in real-time — Clouds (large limits), liquidity zones, imbalance, clusters, volumes, HeatMap, absorption; (4) auto-profiles of settings for each timeframe.

Result: a working web platform with a real-time chart and order-flow indicators at the SBPro level, with automatic switching of profiles by timeframe.

I work in stages with separate evaluations. The most challenging part here is stage 3 (correct calculation of clusters/liquidity/absorption from the flow) — and this is exactly where I have real experience, not "first time by the guide."
…
I will clarify before the evaluation: is Transaq with a specific broker or another gateway, and is the platform needed for viewing by a single user or with multi-accounts — this affects the architecture and timelines.

Examples of work: Freelancehunt · https://guardlabs.online

Approximately stages 1-2 (API + real-time chart): 20000 UAH, ~10 days. I will provide a full evaluation for stages 3-4 after clarifications.

Good day! My partner and I have over 4 years of experience in IT and are ready to implement a trading web platform with real-time market data integration - we will develop API connections, server-side processing of data streams, an interactive chart with support for timeframes and indicators, as well as implement the display of clusters, liquidity, Clouds, HeatMap, Imbalance, and other elements in the SBPro style. We will also separately configure automatic indicator profiles for different timeframes with dynamic parameter application.

Hello Ruslan!

I have reviewed the task.
For such systems, it is critically important to build the processing of streaming data correctly from the start, as this directly affects the performance of the chart, the stability of the indicators, and the ability to scale further without reworking the architecture.

As an option, the TradingView Charting Library can be used for the graphical part, while the logic for data processing, indicator calculations, and stream handling can be moved to a separate backend service. This approach simplifies maintenance and allows for the painless addition of new tools, data sources, or analysis algorithms.

It is also worth immediately planning a centralized system for profiles and indicator settings, so that parameters for different timeframes change automatically and can be edited without making changes to the code.

… I am ready to discuss the details of implementation, data sources, and propose an architecture for the further development of the platform.

I see the task: a real-time trading platform with cluster analysis and order book data from Transaq. A similar architecture has been encountered in B2B products, where it was necessary to pull and aggregate large streams of data in real-time while keeping the UI responsive.

The stack matches perfectly: NestJS for the WebSocket layer between the Transaq API and the client, Vue/Nuxt for the interface itself. I am well acquainted with TradingView Lightweight Charts, having integrated custom series - exactly what is needed for Clouds, HeatMap, and liquidity zones over candles. Clusters and imbalances can be drawn as custom primitives, with auto-profiles for each timeframe through config mapping M1/M5/M15/H1.

I am not yet familiar with the specifics of the Transaq API in detail, but it is an XML/TCP protocol - I have already skimmed through the documentation, nothing fundamentally complicated. PostgreSQL will be suitable for storing tick data and candle aggregates.

I am ready to discuss the details and start in the near future.

Hello! I am a web developer with experience in creating complex financial and analytical platforms.
My hourly rate is $20/hour.
Your task is completely clear to me.
I have experience working with exchange APIs and visualizing volume analysis (Order Flow/Cluster analysis).
I am ready to implement this project step by step:
The tech stack I propose: Backend: Node.js (NestJS) or Python (FastAPI) — for fast processing of Transaq API via WebSockets. Frontend: React.js / TypeScript.
Charts: TradingView Charting Library (if maximum tooling is needed) or Lightweight Charts (if rendering speed of clusters is a priority).

Implementation plan for your stages:
… Stage 1. Connecting to Transaq API
I will set up a stable connection to the Transaq API.
I will implement streaming quotes (FX, XAU/USD, indices) in real time.
I will create an architecture for data storage and transmission via WebSockets to the frontend without delays.

Stage 2. Web Chart
I will integrate the chosen chart library.
I will add flexible scaling, time frame switching, and basic indicators.
I will create custom layers (Panes/Overlays) to display data.

Stage 3. SBPro indicator analogs
Clusters: Displaying Bid/Ask within each candle (Footprint).
Clouds & HeatMap: Displaying market depth (DOM) and large limits as a color heat map in the background of the chart.
Imbalance / Absorption: Mathematical calculation of market order delta and automatic highlighting of levels on the chart in real time.

Stage 4. Automatic indicator profiles.
I will develop a system of dynamic configurations (Dynamic Profiles).
I will tie volume filters (e.g., Clouds) to specific time frames (M1, M5, H1 ...).
When switching time frames, the chart will automatically and instantly recalculate and redraw levels.

Always in touch and working transparently.
For a more accurate estimate of timelines, I suggest chatting in the chat.

It would be great if you could provide documentation.

Good day.

I can join the development of such a web platform.

I have experience with web development, APIs, real-time data, backend logic, charts, WebSocket, and complex integrations. For the task, I would not start immediately with all indicators, but would create a proper MVP: connecting to the Transaq API, data transmission to the server, web chart, real-time updates, and 1–2 key indicators to check the logic.

Then we can gradually add Clouds, HeatMap, clusters, liquidity, profiles for timeframes, and bring everything to a complete platform.

Approximately:
… MVP — from 4–7 weeks
budget — from 120,000 UAH

I will provide a full estimate after understanding the access to the API, data format, required tools, and whether there is already a design/a ready part of the platform.

Message me privately - I will show examples of my work and suggest how to better break the project into stages without unnecessary risk.

Is it more important for you to quickly get a working chart with live data, or to immediately replicate the SBPro logic with all indicators?

Good day!

This is an interesting project. I have over 10 years of experience in web development, working with PHP (Laravel, Yii2), JavaScript, API integrations, and real-time systems.

I am familiar with trading topics, particularly with cluster analysis, liquidity, HeatMap, Order Flow, and the principles of tools like SBPro. I understand the difference between regular exchange data and data for building clusters, volumes, imbalances, and liquidity zones.

From the description, I see several separate blocks:

- data retrieval and processing via Transaq API;
… - server-side processing of real-time data stream;
- building an interactive chart;
- implementation of indicators and visualizations;
- profile system and automatic settings for different timeframes.

Before providing an accurate estimate, I would like to clarify a few points:

- is there access to the documentation and test environment of Transaq;
- is a complete replication of SBPro indicators logic required, or are functional analogs sufficient;
- what is the expected number of simultaneous users;
- is there a plan for further expansion into a full-fledged trading platform.

The main question for you:
Does the Transaq API provide enough data to build these indicators?
If the API only provides candles and a standard order book, some SBPro functions may either be impossible to implement or will require building a custom data accumulation and processing system.

I already have some developments in the trading sphere, not sure if they align with your area of interest, but still.

I am ready to discuss the architecture, timelines, and phased implementation of the project. I can also assist with a technical assessment of the complexity of individual modules before the development starts.

The reality of trading platforms often converges on one point: without proper data synchronization and liquidity processing, even the worst chart will become an ineffective tool.

Your project requires not just the integration of the Transaq API — it is a full-fledged pipeline system for processing market data with a level of detail that exceeds standard platforms by 10 times. It is important to ensure the optimization of order volume flows and speed during dynamic operations on the chart.

The proposed solution will include a module for parallel processing of indicators, built-in profiling mechanics for timeframes, and effective data clustering. An important factor will be the use of high-speed caching patterns for HeatMap and Clouds.

Do you already have a pilot project or an SBPro database for testing the integration?

Hello, Ruslan.

We can connect to the development of a web platform for trading with integration of market data, real-time charts, and display of clusters, liquidity, and HeatMap.

In your project, it is important not just to display a chart, but to properly think through the architecture: data retrieval via API, transmission to the server, WebSocket updates, efficient display of indicators on the chart, and automatic profiles for different timeframes.

We can implement an interactive chart using TradingView Charting Library or Lightweight Charts, as well as custom logic for Clouds, liquidity zones, imbalance, clusters, volumes, and absorption.

Before starting, we will propose a technical structure for implementation to immediately agree on how data, indicators, and real-time updates will be processed.
