Automated Expert System

 

Yo!

With pretty new with MetaTrader platform, but could someone provide any system which actually technically works at all with metatrader ?

Now I don´t mean it necessary need to make any money, but I had tried several systems located in this forum

and some other´s as well to learn this languuge. None of them work out, nothing happen. My system tester will not give any results either

and when applied for production (attatched to the chart) nothing is happening either, just completely different error messages appears in the logfile.

Does anyone have for example simple RSI30 buy & RSI70 sell robocode available for any pair ? Limit per 1 open order at time only and with capable to modify lots size would be nice features.

Basically I would like to receive such a simple template to learn programming a bit myself, propably I would be able to modify technical criterias by editing such a existing template ?

Thankx in Advance

(if there´s anyone during the hot summer wondering metatrader)

 

Just make sure that your Expert Advisor is enabled: Tools => Options => Expert Advisor - check Enable EA and Allow live trading.

That could fix your problem..

Yes, It´s checked jirimac - was all the time.

And I do have currently 1 min eur-usd program as trading which should trade very fast based for 1 minute chart..

In fact I finally managed to find one system which worked out in system tester.

Compile didn´t give any erros at least, but should this for example to do something ?
