WalkForwardOptimizer

5
WalkForwardOptimizer library allows you to perform rolling and cluster walk-forward optimization of expert advisers (EA) in MetaTrader 4.

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. Then you can view and analyse the results by means of accompanying script WalkForwardReporter, which generates comprehensible reports as html-pages. The script is free.

The magic of this EA is that it recognizes the objects that you draw on the chart by closing the open positions at key levels, it will notify you through the mobile notification, then it will wait for the next direction. It opens orders continuously regardless of the time frame of the chart. So you don't have to stay on a lower time frame. Instead, you c

You can choose any time frame as you wish. Every time frame is optimized by its own. Built on new underlying algorithms it makes it even easier to identify and confirm potential trades. This is because it graphically show

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.

This non-trading expert utilizes so called custom symbols feature ( available in MQL API as well) to build renko charts based on history of real ticks of selected standard symbol. RenkoFromRealTicks generates custom symbol quotes, thus you may open many charts to apply different EAs and indicators to the renko. It also transmits real ticks to update renko charts in real time. The generated renko chart uses M1 timeframe. It makes no sense to switch the renko chart to a timeframe other than M1. T

This indicator is an extended implementation of Weis waves. It builds Weis waves on absolute volumes (which is the classical approach) or delta of volumes (unique feature) using different methods of wave formation and visualization. It works with real volumes, if available, or with tick volumes otherwise, but also provides an option to use so called "true volume surrogates", as an artificial substitution for missing real volumes (for example, for Forex symbols), which was introduced in correspo

Classical ADX revamped to provide faster and more solid trading signals. This indicator calculates ADX values using standard formulae, but excludes operation of taking the module of ADX values, which is forcedly added into ADX for some reason.

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? This indicator helps to solve this problem. It builds a complete set of virtual lines of resistance and support around current price and calculates density function for spatial distributi

Mirror

The indicator has three parameters: predict - the number of bars for prediction (24 by default); depth - the number of past bars that will be used as mirror points; for all depth mirroring points an MA is calculated and drawn on the ch

This library is a must have if you are trying to do a Walk Forward Analysis on MT4, and the author was very helpful when I had asked him questions. I would rent again!

Rispondi alla recensione
Versione 1.6 2020.10.19
Numerous fixes and improvements.
- 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.
- 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 with the following prototype: typedef double (*FUNCPTR_WFO_CUSTOM)(const datetime startDate, const datetime splitDate, const double &map[/*size of enum WFO_STATS_MAP*/]); (consult with the documentation and the header file for details).
- New predefined variables is added to the formula engine: AR - average return, i.e. average % of return on a deal (profit/loss amount divided by current balance, averaged on all trades) - this is a measure of balance curve slope, used in sharpe; STDEV - standard deviation of balance curve.
- Forward step size can now be equal to window size (in previous versions forward step should have been less than window).

For any market product, it's recommended to backup exising version before upgrading to the new one.
Versione 1.5 2019.08.22
Fixed a bug with datetime increments overflow, which could lead to multiple empty forward passes with zero dates 1970.01.01.
Versione 1.4 2017.06.13
Fixed an overflow error in calculation of forward steps for window sizes larger than approximately 2 years.
Versione 1.3 2017.05.23
Performance is improved by means of early drop off of those optimization passes, for which in-sample data overlaps with ending date of the tester. Such passes will fail in OnInit with INIT_PARAMETERS_INCORRECT errors. This is an intended behavior.
Versione 1.2 2016.08.29
New function void wfo_setCleanUpTimeout(int seconds) added, allowing you to simplify automatic deletion of old csv-files in Tester/Files and WF_-global variables, the presence of which could lead to incorrect data state after next optimization run. For details - see documentation and Comments section.

Processing of optimization windows which runs out of ending date of test period is fixed.
