Good morning ! Our broker had a problem today and the signal was not available when the market opened. - picture : Capturar(1) When the signal returned, all my EAs were not working probably due to some internal MT parameter change. The history shows OnDeinit() reason 8 (Another reason) - picture

What is the difference between Indicator and EA ?

I have written an EA which takes trade positions (buy/sell) on bar openings. Suppose the EA is attached to a chart of H1 time-frame, the the EA will make trading decision on the opening of a new bar (i.e. every hour), and if the decision is a go, it does the trade (either buy or sell). You can have...

Hi everyone, after doing some research about ECN bokers, I've rewritten my EA to do not send SLTP attributes when invoking OrderSend, but rather modify them right after the order has been accepted. However I encountered a little problem: If I already got a position (let's say a LONG one), and I...

Hey, Is it possible for me to subscribe to a signal with standard account while I am using my nano/cent account? or will that mess up the lot sizing system? Please help me. Thanks

Good morning! Does anyone know how to setup thecolumns we want to see every time we run ST? Even if I change the columns layoutleaving just the ones I want to see, every time we re-run the tests, the defaultsetup brings all the columns back (pict attached) Can I somehow fix that? Regards, MRC

Hello, I have a (maybe understanding) problem with indicators created from the classes provided by the standard library. I want to write a class including a mixture of custom an prefined indicators. In my case I´ve created an instance of the CiDeMarker class within the Oscilators. The class...

I heard MT4 was portable, so I recently downloaded MT4 onto my external so that I can work on code while I'm not on my home desktop. I can access the terminal and charts fine, but I can't access meta editor. Pressing f4/clicking on it in the terminal doesn't bring anything up, and if I try to open...

Hi everybody, I really need you help: I have an expert advisor that usesChartIndicatorAdd() to show in a sub window an indicator. Inside thisindicator, there is a call to another indicator. (The second one is necessary to compute the first one.) This second one in not shownin the Strategy tester...

Sometimes the indicator gives a different reality to the one we expected. While we are not the ones who can read the future state with certainty. Indicator is needed, but the strategy remains the more mainstream. If we managed to combine the indicators and strategies ... of course it will sound...

Hi, This may be a stupid question but hopefully it's possible! I have an EA that I'm testing on MT4 (not mine, one that I purchased) however it doesn't implement a stop loss. Rather than manually managing trades that go really sour, is there some way to automatically put in a SL at a certain level...

To compare 1.36 with 1.36 i need to use if(CompareDoubles(x , y)){ // the same } But how to compare like this ? if ( 1.36 >= 1.36 ){ ? Does this bug with compare doubles are only with == ? or with > < too ? thanks the only correct way in my mind is: if(CompareDoubles(x , y) || x > y){...

Hi all, It's my first post here. I'm starting to learn about EA recebtly, and I've a doubt about time functions. I've been looking for a code that allow to buy/sell at a specific time, but I only found examples that work with a time value of HH:MM. What about seconds? Is it possible to define a...
