Hi what is your sell strategy when you are looking to close a trade?

Do you wait until you hit your predefined limit and take the profit or do you just let it ride as far as possible.

For example on my trading platform I have the option to set a take profit where I could set it to execute at 100%. Meaning I would get my original investment back at have the rest to re-invest.

Or would you just leave it to go as far as possible maybe like 2x,3x,4x

I am always wary about closing positions.
