Here is a code which you can use in an Expert Advisors to automatically adjust variables depending on if the Broker is 4 digits or 5 digits pricing.
following code should be inside the int Init() function
Code:if(Digits==5 || Digits==3){ StopLoss= Stoploss * 10; // this adjusts Stoploss variable for 5digit broker }

Following is a custom function which when called will return total of active trades for a particular magic number:
Code:int CountAllTrades(int magic) { int c=0; for (int j=OrdersTotal()-1;j>=0;j--) { OrderSelect(j,SELECT_BY_POS,MODE_TRADES); if (OrderSymbol()==Symbol() && OrderMagicNumber()==magic) c++; } return(c); }

Though trading on financial markets involves high risk, it can still generate extra income in case you apply the right approach. By choosing a reliable broker such as InstaForex you get access to the international financial markets and open your way towards financial independence. You can sign up here.
This function will close All open trades for a particual MagicNumber of EA.
Code:void CloseAll() { int total = OrdersTotal(); for(int i=total-1;i>=0;i--) { OrderSelect(i, SELECT_BY_POS); int type = OrderType(); if (OrderSymbol()==Symbol() && (OrderMagicNumber() == MagicNumber)) { //-- Close open BUYs if (type == OP_BUY) OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_BID),Slippage,CornflowerBlue); //-- Close open SELLS if (type == OP_SELL) OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_ASK),Slippage,CornflowerBlue); } } return; }

If you have request for any specific code function, please feel free to post your request here and will that code posted to you here in this thread.
Of if you have own own custom codes and you think will benefit other EA programmers, please feel to post it here for the benefit of all.

Here is the code function that will return the chart period in the nicely formation text line.
Example: (if EA is running on 1hour chart)
chartperiod = periodToString(Period()) // will return 1 Hour
Code:string periodToString(int tf) { string tfString; switch (tf) { case 1: tfString = "1 Min"; break; case 5: tfString = "5 Min"; break; case 15: tfString = "15 Min"; break; case 30: tfString = "30 Min"; break; case 60: tfString = "1 Hour"; break; case 240: tfString = "4 Hour"; break; case 1440: tfString = "Daily"; break; case 10080: tfString = "Weekly"; break; case 40320: tfString = "Monthly"; break; default: tfString = "Unknown"; } return (tfString); }

Here is the Code that you can put in any EA to take a screenshot of the Chart and save it to disk, you can call this on any event like if there is any new trade taken, you can save the screenshot.
the system function to take screenshot is:
Code:WindowScreenShot(filename,size_x,size_y)
Here is the example usage:
Code:string filename= "Chart"+Symbol(); WindowScreenShot(filename,570,428)
The above will save the chart with name "ChartEURUSD". You can make the filename very dynamic so every time screenshot is taken, it would save it with different name.

Here is a code which can be saved as a script file in the Scripts Folder.
To execute the script, drage and drop the script on the current chart, this will close all open trades and also pending orders of all symbols.
Code:int start() { double total; int cnt; while(OrdersTotal()>0) { // close opened orders first total = OrdersTotal(); for (cnt = total ; cnt >=0 ; cnt--) { if(OrderSelect(cnt,SELECT_BY_POS,MODE_TRADES)) { switch(OrderType()) { case OP_BUY : RefreshRates(); OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_BID),3,Violet);break; case OP_SELL : RefreshRates(); OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_ASK),3,Violet); break; } } } // and close pending total = OrdersTotal(); for (cnt = total ; cnt >=0 ; cnt--) { if(OrderSelect(cnt,SELECT_BY_POS,MODE_TRADES)) { switch(OrderType()) { case OP_BUYLIMIT :OrderDelete(OrderTicket()); break; case OP_SELLLIMIT :OrderDelete(OrderTicket()); break; case OP_BUYSTOP :OrderDelete(OrderTicket()); break; case OP_SELLSTOP :OrderDelete(OrderTicket()); break; } } } } return(0); }
