Short Trend Reversal

This EA is a part of my other EA Nash Equilibrium. If you activate this EA on a chart created from Nash Equilibrium, orders can be managed by Nash Equilibrium with Manage mode (External or Main&External). EAs are compatible.

With this EA you can build a good profitable system. The EA was created to test signals for the Nash Equilibrium EA, but when I saw the backtest results, I thought I would add a few lines and put it on the market. It works on any classic currency pair /you just need to find the right settings/. It works on many other instruments, but you need to choose the right TakeProfit, StopLoss, min_dist, pending_dist. If you want to test other instruments, it is best to do large tests from methodology 2 with your own TP.

For EUR,USD,GBP,CHF,CAD,JPY,AUD,NZD between them crosses, pips calculated as for a 4-digit broker (inside multiplied by 10). The rest of the instruments as your broker has.
EA has the following Built-in settings: SAFE, MODERATE, AGGRESIVE, start by checking what it looks like with your broker /it was backtested with Vantage broker on STP account/.
I recommend turning EA on several charts of one currency, for example several crosses EUR or USD or ... or mixed, and several TFs, this way you will obtain indirect hedging.

Important: This EA should have StopLoss set to 0 while running. StopLoss is only used to create a statistical file in the tester folder during historical testing. There you will see useful information about the amounts of losing and profitable trades. Pips in this EA are calculated as for 4-digit-broker /FOR CURRENCIES ONLY/. The rest of the instruments as your broker has.

Rules and my backtest methodology:

1. Disable the genetic algorithm if you want to use my statistics file
2. Open prices only testing model. There is no need to test every tick because EA takes a position only on new candles
3. set mine TP first: M15: TP=15, M30: TP=20, H1: TP=30, H4: TP=40 /change if you want, but try mine/
4. EA not using StopLoss. Used only in method 1 for check signals quality

_________________________________________________________________________________________________________

method 1 /detailed/

step one:

• EA default values: and disable the final_optimisation parameter (enabled, averages trades, and we don't want that now), Built-in settings set to 'user'
• BarsRange1: range 5-50 with step 5 (pattern higher lower trades)
• BarsRange2: range 3-13 with step 2 (pattern higher lower trades)
• TakeProfit as above (unless you prefer otherwise, I recommend mine to start with)
• StopLoss you accept (100,150,200 it depends on the symbol and is only used to count bad signals)

Run optimisation with BarsRange1 and BarsRange2 selected. The results that the tester shows or does not show are not important. Important information is saved in the MT4/tester/files/ShortTrendReversal/*.txt file. The file is only created when StopLoss is greater than 0. Now open the created file. I recommend notepad++ for this because it reloads the file if it changes. Analyze the results.

Important: Once you have changed the optimisation parameters, you should clear the tester's cache, as the results will not appear in the html file. (when the tester finds results in the cache, it skips the calculations)

step two:

• narrow the ranges of BarsRange1 and 2
• min_dist:       range 20-90 with step 10 /minimum distance from the previous order, 0 completely disables the limit/
• pending_dist: range 20-90 with step 10 /pending order distance, 0 disables pending orders/
• StopLoss set to 0
• enable final_optimisation

Run optimisation. Now choose what suits you. Additionally, once you have your optimisation results, you can set StopLoss as above call up the individual results. At this point /with StopLoss/ the result itself won't matter, but you can see and compare the new statistics in the file (MT4/tester/files/ShortTrendReversal/*.txt). Statistics will be different than before and will certainly be very helpful in making decisions. You can save selected results to a file with external parameters (MQL4/files/ShortTrendReversal/ReadFromFile.txt). Details can be found in the file.

My rules when backtesting Built-in settings: SAFE,MODERATE,AGGRESIVE

method 2 /fast and simple/ source code and optimisation sets: StrategyTester in pips

Everything as above in one go.

• from EA default settings: change Built-in settings to 'user'
• BarsRange1:   range 5-50 with step 5 /pattern higher lower trades/
• BarsRange2:   range 3-13 with step 2 /pattern higher lower trades/
• min_dist:       range 20-90 with step 10 /minimum distance from the previous order, 0 completely disables the limit/
• pending_dist: range 20-90 with step 10 /pending order distance, 0 disables pending orders/
• TakeProfit set my TP first: M15: TP=15, M30: TP=20, H1: TP=30, H4: TP=40
• StopLoss set to 0
• enable final_optimisation
• enable StrategyTester in pips
• set filter rules

Run optimisation. When finished, open the HTML file from the tester directory, sort, select the good results, deselect the automatically selected ones if you want, and save to a CSV file in the 'csv_done' directory. Now deselect the previous optimisation parameters, enable 'test selected results' and select ONLY the 'stage1 results array' optimisation, e.g. in the range 1-200. Empty ones will be skipped. Now choose what suits you. If you test a single parameter setting, it will be displayed in the tester logs.

Important: Once you have changed the optimisation parameters, you should clear the tester's cache, as the results will not appear in the html file. (when the tester finds results in the cache, it skips the calculations)
Below is a .bat script for quick cleaning cache and delete last created file inside tester folders.

rem @echo off
set mt4_path="full_path_to_metatrader4\tester\files\ShortTrendReversal"
del %mt4_path%\..\..\caches\*.* /P
del %mt4_path%\..\..\history\*.* /P
for /F %%a in ('dir /B /O:-D /A:-D /T:C %mt4_path%\*.html') do del /P "%mt4_path%\%%a"&goto deldone
:deldone
for /F %%a in ('dir /B /O:-D /A:-D /T:C %mt4_path%\csv_done\*.html') do del /P "%mt4_path%\csv_done\%%a"&goto deldone
:deldone
pause

Settings:

Built-in settings:                           user: all settings can be changed by the user for use or backtesting

SAFE,MODERATE,AGGRESIVE:         all parameters from the first section are permanently set:

•     BarsRange1, BarsRange2, min_dist, pending_dist are saved in arrays
•     TakeProfit: M15: TP=15, M30: TP=20, H1: TP=30, H4: TP=40
•     StopLoss is set to 0
•     final_optimisation is enabled

ReadFromFile:    During the first launch, EA will create a ReadFromFile.txt file in the folder MQL4/files/ShortTrendReversal/ with a saved SAFE table as an example of use. After backtesting, you can save the parameters there and you don't have to do anything else. This option not working on VPS.

Due to the fact that importing external DLL libraries is prohibited, I moved the window resize to the indicator. Source code below.
