Hello All,
I recently starting learning to program and test automated trading systems in NinjaTrader. I am using the free historical data that comes with the platform for back testing.
My trading strategy I try to develop are usually with RR>2. I do not develop scalping systems cause I have notice lack of intrabar granularity (incorrect price movement in the small time chart bars) can lead to incorrect profit or loss of the trade.
May I please have your honest and recommended opinion/advice to the following concern:
Questions:
1. How did you gain confidence, reliability and consistence in the backtesting historical data from your platform? Currently, i am developing intra days strategies (all positions closed by end of market session) and rely on platform free historical data to provide accurate back test results for strategies from the 3 min to 1 hour chart.
My Plan Test datafeed reliability and accuracy:
1. Choose a range (1-4 months) from the back test a strategy where there was lots of shorts and long trades, equally. About 100-200 trades. Document each trade.
2. Market Replay the range in step 1. Document each trade.
3. Manual Back test the range from step 1. Document each trade.
4. Compare each documented trades from the previous steps for accurate.
In conclusion, I hope for 90-100% accuracy between each documented performance. Likely, step 2 and 3 should be very similar.
What did you do to gain confidence that every time you click "back test", you had some belief in the performance report?
Please share your comments or thoughts.
Thanks
