Hello! The task is clear. I have extensive experience working with crypto exchanges and Node.js.
To implement support for 18 exchanges and unify the data, I will use the CCXT library. This will allow:
1. To have a single interface for all 18 exchanges (Binance, Bybit, OKX, and others).
2. To automatically normalize OHLCV data (some exchanges return arrays, some objects - I will consolidate everything to your format).
3. To work effectively with Rate Limits (request limits) so that the API does not get banned.
Regarding the merging logic:
I will implement an algorithm that takes timestamps from both exchanges and correctly matches them (merges), filling in gaps with null or previous values if there were no trades on one of the exchanges at that moment.
The project will be in pure TypeScript with strict typing.
Estimate:
🕒 Deadline: 2-3 days (most of the time will be spent testing specific pairs on all 18 exchanges).
💰 Budget: $150 - $250.
I am ready to receive the list of exchanges in private messages.
