Without mechanical trading to eliminate bias you will lose money

Once that has sunk-in the work begins. That's building something from nothing this includes vigorous testing. This stage it's like you are in a lab its trial and error and fine tuning.

Then you roll it out and test it in real world circumstances without deploying any capital.

If you dont have a win rate of >65% and Profit Factor >5 the system needs work. This is the absolute minimum parameters prior to real time testing.

win rate of 50% and Profit Factor 12 is excellent
win rate of 85% and Profit Factor 1 is poor

Understand and let it sink in all systems has losses - if you dont want losses then you need to invest instead as losses are a given and you must take them.

Trading must be seen as a large pool of trades where the numbers behind the system has your back.

Lastly it must be treated as a business. All businesses has trading losses with FY Net Profit Gain and this is not going to be any different. If you made losses two months in a row - STOP what you are doing.
