Description & Settings
An example for calculating the lot value with a fixed margin level. That is, if you specify 10%, a position with the margin equal to 10% of free margin will be opened.
Input Parameters:
StopLoss (in pips) — the stop loss level
% risk — margin for a position as % of free margin
The following loop is implemented to simulate trading:
Initial value count=-21 is set to "warm up" the strategy tester. Then the remainder after devision of count by 980 (this number was chosen randomly) is calculated. It means that every 980 ticks lot calculation cycle is started, in which lot is calculated taking into account the risks per trade.
The lot calculation cycle depending on risk per trade (calculation for the Buy position):
Step one //--- getting lot size for open long position (CMoneyFixedMargin) double sl=0.0; double check_open_long_lot=0.0; //--- variant #1: StopLoss=0.0 sl=0.0; check_open_long_lot=m_money.CheckOpenLong(m_symbol.Ask(),sl); Print("sl=0.0", ", CheckOpenLong: ",DoubleToString(check_open_long_lot,2), ", Balance: ", DoubleToString(m_account.Balance(),2), ", Equity: ", DoubleToString(m_account.Equity(),2), ", FreeMargin: ", DoubleToString(m_account.FreeMargin(),2)); //--- variant #2: StopLoss!=0.0 sl=m_symbol.Bid()-ExtStopLoss; check_open_long_lot=m_money.CheckOpenLong(m_symbol.Ask(),sl); Print("sl=",DoubleToString(sl,m_symbol.Digits()), ", CheckOpenLong: ",DoubleToString(check_open_long_lot,2), ", Balance: ", DoubleToString(m_account.Balance(),2), ", Equity: ", DoubleToString(m_account.Equity(),2), ", FreeMargin: ", DoubleToString(m_account.FreeMargin(),2)); if(check_open_long_lot==0.0) return;
Then the calculated lot value for a Buy position taking into account StopLoss is received to the check_open_long_lot variable using the method of the class:
double check_open_long_lot=m_money.CheckOpenLong(m_symbol.Ask(),m_symbol.Bid()-ExtStopLoss);
The following parameters are printed to the Experts journal: StopLoss, calculated lot value in accordance with the risk per trade, trade account balance at the time of calculation, margin at the moment of calculation.
If the calculation returns "0.0", exit:
if(check_open_long_lot==0.0) return;
Step two
Then we receive the lot value of the Buy position for which we have sufficient funds; the value is received to the chek_volime_lot variable using the CheckVolume method of the class. The following parameters are passed here: m_symbol.Name() — symbol name, check_open_long_lot — position volume we want to open (this parameter was calculated earlier):
//--- check volume before OrderSend to avoid "not enough money" error (CTrade) double chek_volime_lot=m_trade.CheckVolume(m_symbol.Name(),check_open_long_lot,m_symbol.Ask(),ORDER_TYPE_BUY);
Step three
If the CheckVolume method returns a value other than "0.0", then we check the condition: do we have enough money to open a position with the lot calculated in accordance with the risk.
if(chek_volime_lot!=0.0) if(chek_volime_lot>=check_open_long_lot) m_trade.Buy(chek_volime_lot,NULL,m_symbol.Ask(),m_symbol.Bid()-ExtStopLoss,m_symbol.Bid()+ExtStopLoss); else Print("CMoneyFixedRisk lot = ",DoubleToString(check_open_long_lot,2), ", CTrade lot = ",DoubleToString(chek_volime_lot,2));
If we have enough money, open the position, if not — the lot value calculated in accordance with the risk per trade (DoubleToString(check_open_long_lot,2)) and the lot value for wich we have enough funds (DoubleToString(chek_volime_lot,2)) are printed to the Experts journal.

Note that when calculating the lot depending on the risk of free margin, StopLoss does not matter.
