Money Management: Size by Account Balance for FX

In the mean time the following modification works in the MQL4 code:

//+------------------------------------------------------------------+

// Money Management variables

//+------------------------------------------------------------------+

extern string smm = "----------- Money Management - Fixed size -----------";

extern double mmLots = 0.03;

extern double AcctEquity = 0; 

extern double AcctEquityPerSize = 5000;

extern double SizeForAcctEquity = 0.03;

........

.......

then further down in void OnTick

//////////

//+------------------------------------------------------------------+

// -- Functions

//+------------------------------------------------------------------+

void OnTick() {

   AcctEquity=AccountEquity();

   mmLots = MathRound(100* AcctEquity / AcctEquityPerSize * SizeForAcctEquity) / 100;

   if (mmLots <= 0.01) {mmLots = 0.01;}

   sqInitStart();       

   sqManageOrders(MagicNumber);

   openingOrdersAllowed = sqHandleTradingOptions();

AcctEquity=MathMin( AccountEquity(), AccountBalance() );

I fixed an issue with the Current Balance not calculating correctly due to the resizing of the Order PL. The Current Balance appears in the "Comments" field.

I've also added the ability to do a monthly cash injection that will check if the month has changed based on the order.CloseTime, and if it has, it will add the injection amount to the current balance at the start of the month. I've done this based on CloseTime as all other stats relate to CloseTime e.g. order.Size and order.PL
