Hi there, I added some logging code to my EA and due to an ill thought through change, the logging got caught in a tight loop and now, the Experts Tab is spewing out comments. If I shut down MT4 and MT Editor and go back, it keeps on outputting the comments. I've tried deleting log files but nothing...
Hey guys,  I wanted to build a really simple EA based on MT4's built-in Pivot Points indicator that would sell if prices reach resistance levels and buy if they reach support levels. I have not used the iCustom function a lot and so that might be why it does not work although I am not sure since the...

I can obvously do this during...
Hi there, I'm new to MT4/MQ4 and have, with some help from this forum, just created a processing class that effectively produces a collection of values for plotting highs/lows on a chart subject to methodology rules.  When I first started programming MT4, I was just using the Indicator/EA template...
Hi guys I have experienced quite often in MT4 that when an EA sends an order to close orders , a new order gets opened with lot 0.01 and a comment from #somenumber  where somenumber is the number of a trade that was closed. I understand this is something of partial/multiple closing . The existence...
Hi Guys,  First time posting here, with just a quick question about how to approach coding the following into an EA I'm working on.

Anyone had this problem? Terminal.exe starts as a process but no window opens, and it can only be shut down with Task Manager. Last time this happened - complete reinstall followed by hours of setting up indicators and profiles. This time, tried deleting terminal.ini which produced a window with...
Hi, when we limit the number of bars in the chart, the Buffer stays static, with a new bar the value of array [0] not turn array[1] and is overwritten. Is there a simple way to inhibit this, or is necessary to transpose the array using ArrayCopy or copy one value by one value? Thanks

Hello,I wrote a very simple EA based on a custom indicator. Everything was perfect until i tried to change it from selecting by position to selecting by ticket, so that it can be used on multiple pairs. Now, in it's current state, it opens a new order each tick, and does not keep track of the ticket...
Hi, I have noticed that when my EA starts, by default it sets bars not candle. I would prefer have candles since the beginning automatically.  Is there a function that can help me? Regards

Hey guys, I use a button in an indicator and I wonder if it is possible to simulate a mouseclick on a button object? I only know that the visual attributes of a button can be changed with a script but not its function. Do I miss something or is it simply not possible?
