  • Binance Issues Binance options exchange had serious issues which caused Binance MDP not to work in the app. This lead to Balances and Positions not showing. Wrote code to elegantly handle those errors from Binance. Wrote functionality to show accounts in a partially loaded state - like the situation we have today: users can still trade futures if the options exchange is broken.
2.2.22
  • Updated CurrencyConverter: CurrencyConverter keeps conversion path that the user can view by right-clicking balances and positions -> Currency Conversion. CurrencyConverter first makes use of the exchange rates on a particular exchange to do conversions. Failing a lookup there, it falls through to ask Binance and finally CoinGecko for prices. CurrencyConverter breaks up conversions where currenies don't exist on a particular exchage and recursively calls the CurrencyConverter, recombining conversions from those calls.
