APPEARS TO WORK BUT NOT FULLY TESTED

This is a crude "API" for MT4. It allows external programs to control MT4 to execute, modify and delete trades

Store in experts/scripts and compile

Polls folder experts/files every nRepeatDelaySeconds for a file commandfile.txt
If it exists, reads a single trade command as per examples below:

OrderSend,AUDUSD,OP_BUY,1,Ask,5,0,0,1236,9999,0,Orange
OrderSend,AUDUSD,OP_BUYSTOP,1,0.7670,5,0,0,1236,9999,0,Orange
OrderModify,1236,0.7695,0.7620,0.7720,0,Orange
OrderClose,1236,1,Bid,5,Purple
OrderDelete,1236

If the command in commandfile.txt is successful it is deleted and the command is written to commandfile_log.txt
Unsuccessful commandfiles are renamed "FAILED Time[0] commandfile.txt"

Maintains list of open orders in openorders.txt in format:
OrderOpenTime,OrderComment,OrderMagicNumber,OrderSymbol,OrderType,OrderLots,OrderOpenPrice,OrderStopLoss,OrderTakeProfit
