I personally use different strategies.First I test the indicators on the demo chart and test the basics of entry and exit points for different conditions based on various indicators and then I convert them into a single indicator by programming and then I test it in the MetaTrader tester.After thorough reviews I convert my strategy into an Expert Advisor and continue testing again until I am completely satisfied then after final adjustments I run it on the demo account and then the rails.With this method I try to reduce human and emotional error to zero.It has been really fruitful for me.You also write your experiences of the trading process.

Together, we can unlock endless opportunities and achieve your desired results.
