Help me improve my Back-testing

So here I am back-testing support and retest with 200ma and RSI,
To take a tread I have to see if the trend is up or down according to 200ma and conform it with RSI and see if RSI is also agree with EMA .

Then I find the Trond support and see if the retest works and then I enter.

Now what do u think I should add in my back- testing
