Hi Guys,
Hope you are all well. After a break it’s time to review and optimize the Pathfinder 4H robots.
I have checked the DAX version and unfortunately the current DAX market volatility delivers no profits so far. Please find attached a new version V7 containing error fixes, improvements and new features.
V7 release notes:
- fixed the preloadbars error (Thanks manel)
- fixed the error regarding maxPositionSizeShort variable
- fixed the erroneous calculation of the short position size
- add order cumulation for short trades
- add dynamic position sizing based on weekly performance (Thanks Maz for the idea)
- change the rule engine (add previous daily High as short signal)
- remove dynamic max position size calculation
- optimized all relevant parameters
The new dynamic position size calculation based on the weekly performance is responsible for the much better results and of course for the slightly higher drawdown.

ONCE maxDynamicPositionSize = 2 // >1 with dynamic position sizing; 1 without //... // dynamic position sizing based on weekly performance ONCE profitLastWeek = 0 if DayOfWeek <> DayOfWeek[1] and DayOfWeek = 1 then if strategyProfit > profitLastWeek + 1 then positionSize = min(maxDynamicPositionSize, positionSize + 1) // increase risk else positionSize = max(1, positionSize-1) // decrease risk endif profitLastWeek = strategyProfit endif |
The risk is controlled by the variable maxDynamicPositionSize. A value > 1 (default is 2) works as a booster and a value of 1 turns of the feature.
I’ll check the other Pathfinder robots as well.
Best, Reiner
