Coding help needed

[LittleCaro]

Hello all,

I want a little help for coding, i want to know if previous trade was long or short.


So based on this code, i make a bool :

Code: Select all

bool Is previous trade long ()
{

if (OrdersHistoryTotal() == 0) return(false);
   
   for (int cc = OrdersHistoryTotal() - 1; cc >= 0; cc--)
   {
      if (!OrderSelect(cc, SELECT_BY_POS, MODE_HISTORY) ) continue;
      if (OrderMagicNumber() != MagicNumber) continue;
      if (OrderSymbol() != Symbol() ) continue;

But i'm stuck here, how differentiate the longs form the shorts ?

Can someone please could help me to correct my code, thanks a lot !

Use the OrderType() function i.e.

Code: Select all

if (OrderType() == OP_BUY) return(true);

//Got this far, so the order was not a buy
return(false);

You need to put it in the MQL4\Experts folder.

The Cretins at Crapperquotes have taken to hiding the Experts folder away locations impossible to find in Explorer. From your platform, Files/Open data folder will access it.

Add the '/portable' handle to the desktop shortcut forces Empty4 to create the data folder in the location of your chosen Empty4 installation. Right click the desktop shortcut and select Properties. Add '/portable' to the Target field. For example, the Target field for my Blindbot demo:
"C:\Users\piano\Desktop\Trading accounts\Blindbot\terminal.exe" /skipupdate /portable

The '/skipupdate' handle tells Empty4 not to auto-update and is probably irrelevant these days.
