Connecting
An API key, scoped by you
You create the key at Binance and choose what it may do. Grant it only what trading requires: a key that can withdraw is a key that can lose you everything if it ever leaks, and nothing here needs that permission.
Worth knowing
Two Binances, and one has no paper mode
The global venue and the Turkish one are separate connections with separate accounts. The Turkish one has no paper mode, so there is no way to rehearse on it: the first order you send there is real. Plan around that before you connect it, not after.
