Production bug - stop loss related - race condition

[Kamil Skowron]

After initial investigation I believe it's related to stop loss being triggered on order that was filled.

Also, it's worth considering that possibly binance.ex should be extended by new fields like: fills, orderListId or cummulativeQuoteQty
