It does not make sense to me, am I doing anything wrong with asyncio or there is a problem with watch_orders?

User workarounds have to be created, as you suggested - by creating new Exchange instances. However it is difficult/impossible, as the obsolete Exchange objects references cause memory leaks. simple snippet: ```javascript class ExchangeWS { constructor(exchangeName, params) { this.exchangeName = exchangeName; this.params = params; }… [Read the thread](https://github.com/ccxt/ccxt/issues/10786) · 2021-12-06 · closed · external user · 8 comments ### Bybit ccxt.pro watch_positions does not work properly, returns error ### Operating System Wndows 10 ### Programming Languages Python ### CCXT Version 4.1.97 ### Description This example returns error: " bybit does not have market symbol I" All other WS watch_ function work well with this symbol 'ICP/USDT:USDT'.

The orderbook ends with invalid orders hanging there after several hours. I faced similar issue on kucoin as well, however I am unable to debug it deeper as it is (nearly) impossible to compare watched orderbook with fetchOrderBook. You've got an issue there (https://github.com/ccxt/ccxt/issues/10539), with enhancements to be implemented to facilitate debugging these problems. Several expensive lessons 5 months ago on kucoin forced me to… [Read the thread](https://github.com/ccxt/ccxt/issues/12279) · 2022-03-10 · closed · external user · 7 comments ### (fix) Websocket disconnects with 1006 and 1001 errors Hello, A solution has been provided by the Hummingbot community for the bug reported in #14557 and described below.

On Bitget, if specifying only the start timestamp, the result will be starting 1 minute later, which is not consistent with other exchanges behavior. This is due to the way Bitget works: if specifying t start, the candlesticks returned will start at t+1.

E.g., `[[None, 43725.2, 43894.2, 43719.8, 43831.0, 581.0491]]. ` The root cause is that Bingx sends the OHLCV time in the 'T' parameter for "swap", as opposed to the expected "t" used in "spot".
