Hello traders,

Today I have done few trades some of them are good some of them not. But I made one trade that I though it was good but not (USDT-BTC).

So I bought  BTC for 10,754 USDT(green circle on picture) and sell for 10 800 USDT(red circle on picture) but after short period of time price jumped to 11 139 USDT.
I was looking on indicators and oscillator but I didnt see any anything.

Where did I make mistake?

Thanks for every answer
