Poorly executing a strategy.

Hi I’m relevantly new to trading and I’m still using paper, I’ve been sticking to the same strategy for over half a year and have refined it a little over time.

Taking the setup is easy for me now but I struggle because I want to be able to scale into winners as it’s a trend following strategy but can often be taken out the trade. The wr is around 30-40% so being taken out early can be very detrimental. However in the last 3 months I’m still barely profitable but scaling into winners 1 or 2 times would 3x my profit at least. Also I trade on NQ so you know why I might be struggling lol.

I’m open to any advice but I mainly wanted to know how you deal with scaling into winners or just overall improving the execution of your strategy.
