It would be useful to have a boolean field telling if a certain spot symbol supports margin trading.
In Binance that would correspond to the "isMarginTradingAllowed" field:

In OKX it can be indirectly obtained by checking if "lever" is greater than 1 for the instrument:

In FTX, all spot symbols should support margin trading if I'm not mistaken.
