so obviously drawing lines is easy and setting new values to them is easy.. What im trying to do is make a line on the chart that mirrors the bid line and moves with it... As prices moves the line moves with it... But if i manually move the line to a certain level-- it will then stay there..  So its...
Hi All, Recently finished optimising an EA that performed really well on back testing.  Didn't report a single loss. On it's first day of running today however it has drastically failed and has been quite painful to watch. The spread was set correctly on back testing as there is a fixed spread on...
Hi, writing my first EA, which is also my first try in MQL language. Have been programming in other languages for a few years now. The question is : How I can calculate the time difference, since the last time my EA was used ? let's say , I don't want the EA to start , if it's less than 12 hours...
if i create a custom symbol similar to DXY, but which contains all of the symbols in the expert that i want to test then set the back-tester to test on that custom symbol (making sure the symbols actually tested are hard coded into the algo), will i end up with a compiled time-series of ticks for...

My code is mainly in OnTick() Please give me a suggestion what is the cause of this problem and how to fixed it....
Hello everyone! I've two questions: 1) Removing comments from source code would increase the performance of the EA in terms of back-testing speeds? 2) Could some one share a good course (free or paid) to learn MQL5 programming? Thanks! Best Regards, Fernando.
I am just starting to build my first EA. I have written an easy indicator, which is working perfect when attaching to a chart in Meta Trader 5. Also when I debug the indicator all is very fine. As a result from my indicator I can see the arrows plotted to the chart. But when I try to start the...
...like a MQL5 indicator could? Or like WHS Nanotrader can? Not just the default (straight) line, but a curve, e.g. that of a parabolic SL. If yes: how? If no: what‘s next best solution? And will they also show in the strategy tester (backtesting) visualization? Thank you very much!

Hi, I would like some help do code the following EA. I have noticed that EJ often bounce or get rejected at the 100 round numbers (136,135 etc) So what I would like is an EA that place a Sell limit at the upper round number and a Buy limit at the low. The orders should be created when price touch...
I'm new to programming mql4. can you change trade comment when ordersend is rejected (ERR_NOT_ENOUGH_MONEY)? I send this order int OrderSent(symbol,OP_BUYSTOP,1,price,3,stoploss,takeprofit,"recoverBuy",magic,0,clrBlue); if so, how do I change trade comment?
Dear MQL5 community, First of all I'd like to say I'm not the kind of guy to randomly post a question every time I stumble upon an issue. As a matter of fact this is my first post here ever even though I've been using MQL5 for years and coded multiple EAs of varying complexity, some of which running...
Hi! I need to convert a .mql5 file into .mqh so that I can use it in the EA. Is it necessarily to convert the files? Can I just copy and paste it into a robot? Can you also direct me to the documentation to learn the conversion. Your help will be much appreciated. THANKS.
Hello, I would like to know if its possible to edit .mq4 file by script. The point is to permanently change default settings of EA because its to much time consuming work to do that for each EAs when I do massive loading on demo account. I would like to somehow load source code of mq4 file by script...
