Hello @kroitor , I know you have a lot on your mind but did you came with any idea?

The abortion of already running loop is not yet documented. (however, this is related and might get implemented in foreseeable future: #10786 )

@mvazny pardon for the long wait, I'll post an example on how to add watchTicker loops in runtime here.

Are there any updates ?
I am looking for an example on how to dynamically add/remove watchTicker loops during runtime.
Even an "exchange-specific" solution (for binance only) would help me a lot :-)

late reply here, but for context, after that period in ccxt we added watchTickers for many exchanges, so you can use that method.
some notes when using watchTickers:

• some exchanges might be able to watch all tickers, so you can just skip the symbol which you don't want
• if exchange requires list of symbols, then you can easily amend the symbols during runtime, smth like this example:

const ex = new ccxt.pro.binance();
let mySymbols = ['BTC/USDT', 'ETH/USDT'];

async function myWatch () {
    while(true) {
        const result = await ex.watchTickers (mySymbols);
        console.log(result);
    }
}
   
function modifyFunc () {
  mySymbols = ['SOL/USDT']; // etc... modified in another place during runtime
} 

async main() {
    myWatch ();
    await ex.sleep(5000);
    modifyFunc ();
}

main();
