How to go about back testing a strategy

back testing involves testing a strategy on pasts data…i know that but what i’m drooling about is how do i start?
do i just open my meta trader zoom out to a higher timeframe locate a support and resistance then zoom in on a lower timeframe go back in time and move the charts one candle at a time and see how price reacts to that zones with respect to my strategy?

It’s a good habit to backtest trades. If you won’t even try to find what went wrong with your previous trades, you won’t learn anything. In fact, you will stay stagnant in the market and there will be nothing that can save you from making losses. Learn from your own trades if you want to stay for long.
