Lot calculation Question.

New comment
 

I have an EA.


It instructs:


●       Set The Lot size 0,10 or 0,15 for each $100,000

●       Max Drawdown Expected 3% with this setting


If I use 100 leverage, and I have 10K USD in the demo account, will I use 0.01 lot because it is 10% of 100.000 USD? Or with leverage it will be 10 times more? 


Thank you....

1:100 = $1 is worth $100 in the market, same goes with other ratios. You calculate risk percentage according to market value. 

Lot size is calculated using the following formula: Lot Size = (Risk Amount / (Stop Loss x Pip Value)) x 10,000 For example, if you have a $10,000 account balance, and willing to risk 2% of your account, and the stop loss is 50 pips, the lot size would be calculated as follows: Risk Amount = $10,000 x 0.02 = $200 Pip Value = $10

Risk depends on your initial stop loss, lot size, and the value of the symbol. It does not depend on margin or leverage. No SL means you have infinite risk (on leveraged symbols). Never risk more than a small percentage of your trading funds, certainly less than 2% per trade, 6% account total.

  1. You place the stop where it needs to be — where the reason for the trade is no longer valid. E.g. trading a support bounce, the stop goes below the support. Then you compute your lot size.

  2. AccountBalance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the spread, and DeltaPerLot is usually around $10/PIP, but it takes account of the exchange rates of the pair vs. your account currency.)

  3. Do NOT use TickValue by itself - DeltaPerLot and verify that MODE_TICKVALUE is returning a value in your deposit currency, as promised by the documentation, or whether it is returning a value in the instrument's base currency.

  4. You must normalize lots properly and check against min and max.

  5. You must also check Free Margin to avoid stop out

  6. For MT5, see 'Money Fixed Risk' - MQL5 Code Base (2017)

Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5 or 0.1 Lots maximum.
