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?
What are you doing, scalping the 1-minute time frame?! A 0.428% profit is enough to get
something after fees, but it's not worth the effort to me. I would zoom out and start trading higher time frames if I were you.
There is an incredibly strong bull trend on every time frame from 4-hour to monthly. This trend can overwhelm anything you see on your 1-min or 5-min indicators. Selling short term overbought conditions is really only advisable during range-bound trading. During a strong uptrend like this, you are missing out on much bigger gains by selling too early.
