I have paid a developer to build a trading website for me. The user interface is fine, but the bot wont trade properly. He is totally clueless and has been working on this project for 5 months.
Is there a list of (functional) API wrappers that can be used to execute trades on Bittrex, Binance, Yobit, coinexchange.io, cryptopia, Bit-z, BitFinex, Bibox, BitHumb, Bitstamp, Cex.io, Gemini, HitBtc, Huobi, OKex, and UpBit?
Is there anyone with experience creating these types of tools?
