API Spot/Margin API

Binance currently offers Cancel All Open Orders on a symbol Binance API Documentation.

How do I cancel all open orders by not providing symbol parameter? Even if it’s a workaround…

You must provide a symbol as per the documentation. One approach would be to put the cancel all open orders in a loop and iterate through the relevant symbols.
Eg:

for symbol in symbolList:
    cancelOrder(symbol)
