Calculation for lot size by profit amount

 

Dear guys

I need a calculation to get lot size by profit amount. example i want profit 30$ by 10 pips then how many lot i need to take.

1 lot = 1 pip = 10$ then

10 pips = 30$ = ? lots.

please some one give a right calculation how i lot size

 

10 pips = 30$ then lots = $30/ (10/pip) = 3

Except it's only $10/pip when your account is USD AND pair ends in USD. See https://www.mql5.com/en/forum/147546

 

sorry i didn't get.

My question was :

if 1pips and 10$ profit = 1lot.

then

30$profit and 10pips = ? lots.

Use algebra . . .

1pip * 1lot * x $/lot/pip = $10

so x $/lot/pip = 10 $/lot/pip

Hence

10pips * y lots * 10 $/lot/pip = 30$profit

so y = 30/(10 * 10) = 30/100 = 0.3 lots
