@kevinhpchan Okay replay is not backtesting. Backtesting is where you have fully defined your rules and tested them historically. As for the structured process, you will have to create that. The best simulation of live trading is trading in the simulator on live basis. There are small inaccuracies in most replay engines, unfortunately. In addition, even if the replay engine were accurate, you still have the problem that it is difficult to incorporate non price information or price information on different frequencies. Notice that most traders have adopted the "statistical" perspective on markets even though statistical properties of markets are not very reliable. Many of the large traders, instead, have adopted opportunistic or speculative mindset. As an example, the early adopters of Bitcoin weren't thinking statistically, they were buying opportunistically with an incredible risk to reward ratio. I think that both thinking styles can compliment one another but in the replay you can only practice on statistical basis (unless you have an engine that can also replay the news for a day-- would be nice).

It is what you create. However, if you want to practice then I recommend reducing the number of variants (things that can vary). Most day traders focus on the first and last hours of the session. Given that, focusing on those areas where you plan to trade will be more productive. By reducing the variants, you can improve your confidence of being able to translate the performance into a live account. For example, trading with a max 3 point stop loss is going to be easier to translate into live trading then setting your stop based on your discretion on the fly. Make as much of your trading as invariant as possible is the basic goal. If you can trade well under these invariant conditions, you use realistic to slightly pessimistic fill engine, and go live you should see similar results provided the market doesn't change. As for enhancing the learning process, careful documentation and serious review of your trades will help with that.

One other aspect that needs to be developed is market cognition. The mind of a trader should be active, accurate, and clear during trading.



Thank you so much for the useful advice & recommendations. Iím currently learning how to read Charts using the Whyckoff methodology so I want to learn to apply that in daytrading. After which, I will add in indicators and new setups Iím learning (e.g MBoxWave).

The reason why Iím interested in backtesting with historical data is that I can compress more practice time. I will simultaneously also do live simulation.

A couple questions. Iím still evaluating between NinjaTrader & Sierra Charts. Any perspective how each would fare in replay?
