WalkForwardOptimizer MT5

3.86

WalkForwardOptimizer library allows you to perform rolling and cluster walk-forward optimization of expert advisers (EA) in MetaTrader 5.

To use the library include its header file WalkForwardOptimizer.mqh into your EA source code, add call provided functions as appropriate.

Once the library is embedded into EA, you may start optimization according to the procedure described in the User guide. When it's finished, intermediate results are saved into a CSV file and some special global variables. Also a comprehensible report is generated as HTML page.

Warning! Do not pause optimization process. Clicking Start button (even if it resumes suspended optimization) will rewrite WF results from scratch. MQL5 API does not allow to distinguish new optimization from resumed old one.


This is a library. It requires a user to have some developer skills. If you do not have source codes of your EA (if it's a 3-rd party commercial EA) or do not understand the sources codes (if it's made for you by custom developer), please, contact the author/developer of the EA (source codes) to solve all problems. If he thinks there is a bug in the library, then let the author/developer contact me directly. I need technical details (which are hard to receive from non-developers) to provide proper support.

WOW!! Incredible Tool!! - Such a Time Saver. Pretty Easy To Integrate Also. I have tools that can schedule multiple walk-forwards but the analysis report is worth its weight in gold for determining how often to optimize your EA. Other tools that have walk-forward integrate the 'rolling' option and stats. Why Metatrader didn't is a mystery (will probably update one day). Until its properly added to MT5 this library powerfully fills the gap!

This is a must tool for all system developers. I waited 5 years for someone at Metaquotes to develop a Walk Forward Optimization. Stanislav is a godsend. He managed to create this WFO library utilizing cloud computing. Finally, we have a similar system development tool compared to TradeStation, Multicharts, NinjaTrader and etc. I received a great product and responsive support from the Developer. I highly endorse this product.

Most of traders use resistance and support levels for trading, and many people draw these levels as lines that go through extremums on a chart. When someone does this manually, he normally does this his own way, and every trader finds different lines as important. How can one be sure that his vision is correct?

WOW!! Incredible Tool!! - Such a Time Saver. Pretty Easy To Integrate Also. I have tools that can schedule multiple walk-forwards but the analysis report is worth its weight in gold for determining how often to optimize your EA. Other tools that have walk-forward integrate the 'rolling' option and stats. Why Metatrader didn't is a mystery (will probably update one day). Until its properly added to MT5 this library powerfully fills the gap!

It should have a better manual. I had some difficulties installing because the automatic deployment doesn't work. And, to put it to use, you need time. The results must show, or indicate, either the best parameters or the main set of parameters (the optimized parameters). For a while, I let side and continue with my method.

This is a must tool for all system developers. I waited 5 years for someone at Metaquotes to develop a Walk Forward Optimization. Stanislav is a godsend. He managed to create this WFO library utilizing cloud computing. Finally, we have a similar system development tool compared to TradeStation, Multicharts, NinjaTrader and etc. I received a great product and responsive support from the Developer. I highly endorse this product.

- In the report, relative drawdown estimate normalized by annual profits/losses is now shown for previously decreasing financial results as 100+% instead of 0.
- In the report, probability estimate of the drawdown is calculated by Monte Carlo method.
Sürüm 1.12 2023.10.26
A new bitwise flag for wfo_setAdvancedOptions function is added, which allows for resuming a paused slow/complete optimization or repeating a genetic optimization.
Sürüm 1.11 2020.10.04
Validation of standard meta-parameters (introduced in version 1.10) is made optional for easier intergation into custom EAs using MQL for internal WFO setup.

- New experimental mode added: now you can specify forward step size not only in percents, but in days as well. To enable the mode enter negative values for wfo_customStepSizePercent. For example, optimization triplet [start, step, stop] can be [-10, -5, -50] to check forward steps of 10, 15, 20, 25, 30, 35, 40, 45, 50 days. Positive values work as before, presenting percents.
- Forward step size can now be equal to window size (in previous versions forward step should have been less than window).
- New function wfo_setAdvancedOptions(const ulong flags).
- Anchored mode restored (was accidentally disabled in 1.8).
- More diagnostic information provided in logs and reports.

Please find updated header file in Comments.

Improved diagnosis of potential problems in setup, additional details are shown now in logs and in html-report.
Sürüm 1.8 2020.05.16
Minor bugfixes and improvements.

- The passes with numbers greater than 9007199254740992 will be skipped, as they lead to double overflow.

- Zero divide error for the rare situation with no valid passes is fixed.

- The ending date of forward period is excluded now - the same as in the tester.

- Expression evaluation engine for custom formulae is replaced with completely new one. In addition to previously supported operations, it handles now unary minus and logical negation, as well as ternary conditional statements w?t:f.

- The last parameter of FUNCPTR_WFO_CUSTOM prototype is changed to accept an array of doubles instead of a map: typedef double (*FUNCPTR_WFO_CUSTOM)(const datetime startDate, const datetime splitDate, const double &map[/*enum WFO_STATS_MAP size*/]);

- More changes in the html-report builder.

Improvement: New function wfo_setCustomPerformanceMeter(FUNCPTR_WFO_CUSTOM funcptr) is added. It allows you to pass a reference to your special custom callback into the library. This callback function will be called by the library to get your custom trade efficiency mark (OnTester analogue). This can be handy if the existing approach with formula assigned via wfo_setEstimationMethod(WFO_ESTIMATION_METHOD estimation, string formula) is not sufficient for you. In the expert code one should implement a function of type FUNCPTR_WFO_CUSTOM (consult with the documentation for details).
