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
Hey guys im copying a system that uses 8700 dollars in deposit and 1:500 leverage. i have 3500 usd on mine and 1:500 leverage. Is the program (mt4) going to copy the volumes EXACTLY (1:1) as his or will it adjust it down according to MY deposit and not the provider's? That is if i have 1/3rd of his deposit (3500$ and not 8000$ does it automatically trade 1/3rd of the lot size aswell given that we have the same leverage allowed? Eg provider's trade: 1 Lot. My trade 0,33 lots?
In order to copy with same lot size you must have the same leverage and currency and a bit more balance than the signal provider, since you can only use up to 95% in signal copying.
You must have 100% copying ratio (or more), so check for it in the MQL5 VPS or your computer's journal.

Hey thanks for answering. I have calculated everything but im just wondering if all these adjustments on lot size will be perforemd automatically by MT4 or if i have to do something myself?

Yes, automatically, if you add to your balance, the lot size will be increased.
