You can calculate your lot size using the following example (from General information on Trading Signals for MetaTrader 4 and MetaTrader 5 article):
Let's consider a specific example of using the volumes management system:
- Provider: balance 15 000 USD, leverage 1:100
- Subscriber1: balance 40 000 EUR, leverage 1:200, deposit load percentage 50%
- Subscriber2: balance 5 000 EUR, leverage 1:50, deposit load percentage 35%
- EURUSD exchange rate = 1.2700
Calculation of Provider's and Subscriber's position volumes ratio:
- Balances ratio considering specified part of the deposit in percentage terms:
Subscriber1: (40 000 * 0,5) / 15 000 = 1,3333 (133.33%)
Subscriber2: (5 000 * 0,35) / 15 000 = 0,1166 (11.66%) - After considering the leverages:
Subscriber1: the leverage of Subscriber1 (1:200) is greater than Provider's one (1:100), thus correction on leverages is not performed
Subscriber2: 0,1166 * (50 / 100) = 0,0583 (5.83%) - After considering currency rates of the deposits at the moment of calculation:
Subscriber1: 1,3333 * 1,2700 = 1,6933 (169.33%)
Subscriber2: 0,0583 * 1,2700 = 0,0741 (7.41%) - Total percentage value after the rounding (performed using a multistep algorithm):
Subscriber1: 160% or 1.6 ratio
Subscriber2: 7% or 0.07 ratio
Thus under the given conditions, Provider's deal with volume of 1 lot will be copied:
- to Subscriber1 account in amount of 160% - volume of 1.6 lots
- to Subscriber2 account in amount of 7% - volume of 0.07 lots
Besides, you may check the Metatrader journal (or MQL5 VPS journal in case you are using MQL5 VPS) because it should be written about why you have this amount of valume.
