Currently, after one strategy finishes executing, the subsequent strategies are not executed; optimize to place multiple orders
bestBid/bestAsk is sometimes fetched inaccurately; use the REST API to periodically calibrate the WS, fetching once every 5 seconds, and reconnect this WS after 3 consecutive readings exceed the threshold
Do a code review and optimize the code
Build a backend-only version for deployment on a cloud server
Crash bug to reproduce (observed that every time memory fills up, the Binance line lags on the time axis, but the data trend is real-time; only the overall line becomes laggy, and the yellow dots also drift toward the left of the x-axis; after switching the time window, memory is released again) <--- Last few GCs --->
