Yes the time span is important. Especially when you are in a trade, you are expecting something to happen, and if it doesn’t you need to get out.

I normally wait for a certain number of candles but I'm a bit random with it.

I cancel orders a lot when trades that I want don't execute in a certain timespan I want/expect.

Thanks for the answers, everyone.
Jeez, I thought it was only me that thinking this because most of my trades that have already been long stayed open without any of my orders being triggered are considered lost.
Now I have my idea, maybe I will start observing my trades and decide how long could my trades will stay if the prices got no reactions at all.
