Manual backtesting is the process of manually scanning charts for transactions that correspond to your trading strategy based on the trading rules established in your trading plan. Manual testing entails scrolling through the bars of a chart in search of suitable trade setups. This can be difficult, and you are prone to making mistakes.
Manual backtesting may not appear to be the most exciting method of evaluating your strategy, but it is an excellent way to see how well the strategy works in different market situations and where adjustments are required.
