Lots calculation; I keep getting 0 lots when debugging

New comment
  
Lots=MathFloor((AccountFreeMargin()*AccountLeverage()*Risk*Point*100)/(Ask*MarketInfo(Symbol(),MODE_LOTSIZE)*MarketInfo(Symbol(),MODE_MINLOT)))*MarketInfo(Symbol(),MODE_MINLOT);
Print(Lots);

When checking the log, I continue to get a calculation of 0 lots, so this error perpetuates:

Perhaps you can explain the logic behind your calculation ? what are you trying to calculate ?
 
I'm trying to calculate lot size (ie: Lots) using risk management. The variable "Risk" is an int that represents the percentage of the account that you are willing to risk in a given trade. All other relevant data within the calculation are built in mql4 functions or constants that should produce an appropriate lot size given Risk value.
 
This is being tested on the Oanda platform.

Your code:

double Lots = 0;
int Risk = 1;
Lots=MathFloor((AccountFreeMargin()*AccountLeverage()*Risk*Point*100)/(Ask*MarketInfo(Symbol(),MODE_LOTSIZE)*MarketInfo(Symbol(),MODE_MINLOT)))*MarketInfo(Symbol(),MODE_MINLOT);
Print(Lots);

produces this in the log:

Lots Test #1

So, the code (as you have posted it) seems to give a non-zero value. Did you define the variable Lots as an int or double?

 
Normalize the size
 
WHRoeder :
Normalize the size

So, basically instead of using MathFloor() I want to use NormalizeLots() ?

How does it ? your risk is governed by your stop, where is your stop in your calculation ?

I missed that post.
Risk = account balance * percent = (OrderOpenPrice - SL) * OrderLots * DeltaPerLot.

Risk = account balance * percent = (OrderOpenPrice - SL) * OrderLots * DeltaPerLot.

Good, I thought it was just me going nuts and being confused about what the OP was trying to do . . .
