Yes, we have two accuracy rate, for example with BTC_USDT pair, and prediction in 5 minutes
We have this chart https://cppts.com/chart/5m/BTCUSDT.html
1. Trend error is accuracy rate based on : how many percent we predict BTC price up is right (or down is right)
2.  Relative error is accuracy rate based on: deviation of usd of each prediction (but it still has some error need to fixed)

The bot trade we continue developing using API from Binance

Thanks and best regards
