expert adviser to buy additional lot when RSI oversold

Dear Traders!
Please help! I need a sample code or an instruction on how to code within MT4 expert adviser the ability to buy additional lot when RSI is below oversold ONLY if there is already an existing trade. In other words how do I code the ability to add into existing trade???
I am not a programmer. I use wizard, but unfortunately this function (to add more lots) is not supported.
Will appreciate any help and guidance.
Kind Regards,
Adilius

You can't add lots to an existing position.

You must 1st check if you have an existing position, then check if your condition apply (OB/OS), then open a new position with your defined additional lot.

Thank you FerruFx. Do you know where can I read more info on how to do it this?

If you are not a coder, the very 1st thing would be to learn the basics before trying to modify a code.

That's absolutely right! Can you share with whatever expert adviser you have that implements the additional entry? I would read and try to understand so I can include the ability to buy additional lot when RSI is oversold in my strategy?
Will appreciate any help with this.

this is rather simple to implement.
you could attach your ea, maybe somebody will do it for you

Hello, fxdaytrader.

I even have the line in ninja script. Asking to convert whole expert will be selfish. I need to do work myself. Just asking to help with this line.



if (
( Position.MarketPosition == MarketPosition.Long ) &&
( RSI( Close, RSIPeriod, RSISmooth )[0] < AddOverSold ) &&
( Close[0] < ( Low[0] + ( ( High[0] - Low[0] ) * ( (double) RangePercent / 100 ) ) ) )
)
EnterLong( "AddBuy" ) ;

What it does is it checks if there is an open trade, if so it will add to existing position when RSI is oversold and the bar closes in lower 30% of its entire range.
Please help. What is the MT4 code line should look ?
