This code doesn't work: struct LockStruct {    int ticket;    int locked; }; orderTicket1 = orderOpen( "buy" ); LockStruct orderTicket1 = {orderTicket1, 1 }; 'orderTicket1' - constant expression required declaration of

I actually avoid coming here, but I've spent 90 minutes trying to solve this big mystery with no success because the documentation absolutely does not help and all examples I find are very complex, seemingly going out of their way to avoid the

if (ProfitToday() <= MaxLoss)    { Print ( "Exceeded. ProfitToday is: " + ProfitToday() + " MaxLoss " + MaxLoss);} The Print log says: Exceeded. ProfitToday is: -1.14 MaxLoss -10 I am confused. I thought -1.14 was > -10. But

I do realize I am doing something stupid, but I'm not quite sure of what and why. I want to get the average size of candles. So I take say, the last 500 candles and measure their bodies with MathAbs (Open[i] - Close[i]); I add them all up. Then I

When I add a horizontal line from the drawing tools menu, I can drag that line. When I add a horizontal line from an EA, I can't drag it. How are they different? Why can I drag one but not the other

I tried to make an EA based on Ichimoku Clouds and soon ran into a silly mistake. When all the conditions are met, the EA opens a trade. For example, long. If you're familiar with Ichimoku Clouds, you know what those conditions are. So the trade hits

for (i = total - 1 ; i >= 0 ; i--) {      if (! OrderSelect (i, SELECT_BY_POS, MODE_TRADES)) continue ;      if (OrderCloseTime() != 0 ) continue ;      if (OrderSymbol() != _Symbol )

I have an EA that only places orders of the BuyStop/SellStop type and only integer values. Of course the variable type has to be double, but the value is always an integer. When the price is touched, the order goes live. In one of my brokers, that

If I have 159.8 I want 159, not 160. MathFloor(), MathCeil() and even NormalizeDouble(number, 0) will round the number. Is there any function that will just drop the fraction and give me the integer without rounding

I have two Internet connections. One of them is working fine. It's just a little slower. The primary one can log on to my brokers (two brokers) and update all the data in the charts, but I can't place or close any orders. When I try to open an order

I have a demo account and a real account with a broker. They both work fine. Now, new broker. I also have two demo accounts with this new broker. They work fine. I opened a real account with the new broker. I click "Login to Trade Account," fill it

I have an EA with a routine that runs OnTick(). It monitors the current chart's pair. But I want the same EA to check other pairs too. The problem is, the routine only runs OnTick() by the current chart's ticks. It can't see ticks in other pairs. Or

I know the MODE_MAIN value is an ordinary moving average . What about UPPER and LOWER? What is the formula for calculating the percent deviation? I know how to use it in MT4. Now I want to know how it is calculated

My broker only provides history for some past period. But scrolling MetaTrader allows me to go past that, including moving averages . How can MT show data and plot a chart including moving averages of history data that is not available? Let's say the

I just noticed Startegy Tester tells me this: 2022.11 . 11 10 : 44 : 03.678 TestGenerator: actual tick file "{installation folder}\tester\history\EURUSD60_0.fxt" found I tried to open that file, but I can't. Is there some way to convert or extract

I want to collect some historical data: TF = 60 ; NumberOfBars = 1000 ; datetime When = iTime ( _Symbol , TF, NumberOfBars); void Collect()   {    Date = IntegerToString (TimeYear(When)) + "-" + IntegerToString (TimeMonth(When)) +

I installed MT4 in a new machine. I copied one EA over from the first machine to the Experts folder in the second machine. Just the ex4 compiled code. No source. The EA ran for two days. It still does. Good. Then I decided to copy another EA. That EA

Maybe my problem is unusual, but it's certainly complicated, and I admit I painted myself into a corner. I have an include file called AllMyFunctions.mqh. All my EAs begin by 'including' that file. Some EAs maye have ad hoc functions, but most

I want to put a cap on losses before I turn off the EA to avoid further damage on a clear bad day. Do you think this is the correct way to do it? starting up: double TodaysEquity = AccountEquity(); double InitialEquity = AccountEquity(); double

I ran an EA and had an interesting result. Not very good, but interesting curves. I have to study it more. Then I ran a second EA, two timeframes. It was worse. Then I ran third EA, two timeframes. Also worse. So I thought about something I should
