Problem creating Autolot configuration
Hello friends,
I am developing a strategy, where i want to use an auto lot configuration, but not based on Stop loss or take profit, i want that the code uses a lot size that is a % of the total balance, for example:
If i have10.000 USD balance in the account and i setup the percentage of balance to be used to 40%, that the EA calculates automatic a lot size configuration for 4.000 USD (40% of 10.000 balance) between the maximum orders and the minimum lot size allowed for this account configurated, so in this case if i have setup to open a maximum of 4 orders for EUR/USD and my minimum lot size is of 0.01 lots and if the lot price is 1600 USD, that the program uses the math:
10.000 (balance) x 0.4 (% to use) / 4 (maximum orders) / (1600/100) (min lot price) x 0.01 (minimum lot) = 0.625 with only 2 digits = 0.63
This way the EA would open a maximum of 4 orders of 0.63 lots for this pair at this moment, allways leaving a 60% of free margin
Is it possible somebody can help me with this, or knows how would this to be a better way of configurating it?
Would this formula be correct?
Is it possible that the code calculates itself the lot price ?
How would it change if i'm using this on sp500 where minimum lot size is 1 lot = 25 USD?
Can somebody send me this code?
thanks in advance,
Daniel
I use this formula. Here the risk is constant and does not depend on the distance between the open and stop:
balance: this is the account balance.
dis: the distance between the price of position opening and stoploss in ticks.
pt: it is price of the tick in USD for one lot.
risk: this risk positions or transactions in percent.
lotstep: it is the minimum step size changes position. In this case it is equal to 0.01.
size: this is size of the position.
Formula where the risk is constant:
x = 100%*dis*pt*lotstep
y = risk*balance/x
y: this is the quantity of the lotstep and y rounded to an integer.
size = lotstep*y
