quick question . max lots expert advisor

[tennisplayer128]

hi, im trying to code a basic expert advisor . at the top of my code I have written   extern double Lots =100;

so that sets the amount of lots my expert advisor trades with to 100 lots . I want to change this. my question is , how can I code my expert advisor to trade the maximum amount of lots possible on every trade ?

instead of writing extern double Lots =100;  what would I write instead of that ? thank you

Do that, and blow your account. But if you insist, make sure you don't get a margin call (stop out.)

• You place the stop where it needs to be - where the reason for the trade is no longer valid.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.
• Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the SPREAD, and DeltaPerLot is usually around $10/pip)
• Do NOT use TickValue by itself - DeltaPerLot
• You must normalize lots properly and check against min and max.
  
• You must also check FreeMargin to avoid stop out

thank you for the response . I know nothing about coding , would I literally just copy and paste this      Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot

instead of writing         extern double Lots =100;

OrderSend(...,MarketInfo(Symbol(),MODE_MAXLOT),...);

And apparently nothing about math - I gave you an equation not code. Top of every page is Freelance

In OrderSend()

In OrderSend()

thank you again . so I just simply copy and paste that simple line of code wherever it says OrderSend and that's all I have to do ? should I delete this line of code extern double Lots =100;   from the top as well ?

yes

if you want EA to open max lots

you need to set MarketInfo(Symbol(),MODE_MAXLOT) in OrderSend function in places where lot must be.
