I cannot find information at Binance: for how much % has each of my coins (positions) have changed since I bought it. I need that information for closing positons since I code in Python.

I am creating the bot which will trade autonomously and it is closing positons via change in % since the time I opened position.

If I have +5% for example I want to sell my coin and 'collect' profit.

I canno find that information at Binance.

Please help!
