HI

DOES ANYONE HAVE BACKTESTED EA CREATED USING MOLANIS STRATEGY BUILDER (MSB). WELL I HAVE PREPARED AN EA USING MOVING AVERAGES BUT WHILE BACKTESTING MT4 CRASHES IT GIVES A LIST OF ALL THE FILES U CAN SEE IN DIRECTORY WHERE MT4 IS INSTALLED AND ONCE U CLICK OK IT WILL EXIT.

I TRIED SEVERAL DIFFERENT BROKERS MT4 PLATFORMS BUT SAME THING IS HAPPENING. I TRIED IT EVEN ON VPS BUT IT CRASHED TOO, IT WAS A DEMO ACCOUNT.

ANY HELP WILL BE MUCH APPRECIATED.

THANKS

Call stack :

Before the beta launch we did several tests related to backtesting and did not find any errors. However, MT4 can not backtest strategies which involve multiple currency pairs. It is likelly that the problem is related to MetaTrader. Can you send your startegy to support@molanis.com for us to backtest?

Hi

its just a simple moving average of 9 and 100 over an hourly timeframe.

currency pair any, lot mgt type 1 stoploss and trailing stop 40.

obviously its a beta version so cant see the mql4 code however i tried attaching ex4 file but doesnt allow it.


thanks

The file we need is the .mol file. It's the file created by Molanis Strategy Builder

i am attaching here the .mol file which was created.

thanks

Your lot size for SELL is 0. This creates an error when sending the order to the server. However this does not lead to MT4 crashing. The MetaTrader crash is not due to the code generated by Molanis Strategy Builder. Instead it's related to MetaTrader. One of the reasons for this issue is related to using different MetaTrader versions. If you compile with one MetaTrader version and trade or backtest with another one, MT4 will crash -sometimes-. This has been mentioned several times in MetaTrader forums. The solution is to install the latest MT4 version and generate the code again.

If you have two or more MetaTrader installations in your pc and MT4 crashes, you need to use the same MT4 version (build) to generate the code and trade/backtest. If you can't install the same version, you need to do the following:

-Go to Molanis installation directory (C:\Molanis\Strategy_Builder)
-Make a copy of the file molanis-pref.xml just in case you need it later. This file contains Molanis configuration parameters.
-Open the file molanis-pref.xml with notepad (or any text editor) and find the line:
<entry key="mt4dir">C:\Program Files\MetaTrader 4</entry>
-Change C:\Program Files\MetaTrader 4 for the directory where your MetaTrader installation -the one you want to use for trading or backtesting- is located. DO NOT CHANGE ANY OTHER LINE!
-Open Molanis Strategy Builder
-Create your strategy with Molanis Strategy Builder (.mol file) and generate your EA

In the next version, we'll make this process friendlier.

If you get this message when generating the MQL code: "Error: The file couldn't be opened on the MetaTrader editor. Please review the MetaTrader settings in Molanis' preference file." the directory you added is wrong. You need to change it.
