How to set custom lot?

jboddie:
I have been using this EA ( http://www.autotradingfx.com/softwares/scalpnetv13 ) as my starting point. I have changed all the lots in the meta editing to 0.01, now i would like to change this to be able to choose my custom lot by putting it in the settings when loading the EA to chart. I want to be able to have a large range in being able to choose what lot i like instead of having to go to the meta editor every time i want to change the lot. Is it the risk setting of 0.15 that is limiting my lots?

you have to set the lots variable as an external...like this:

extern double Lots =0.01; // place right at the top just under the #property copyright "" and #property link ""

now replace the lots value in the ordersend function with the word Lots, like this :

old ordersend : OrderSend(Symbol(),OP_BUY,0.01,Ask,3,0,Ask+TakeProfit*Point,"macd sample",16384,0,Green);

change to : OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,Ask+TakeProfit*Point,"macd sample",16384,0,Green);

Yeah i have the "external" in the script. You will have to look at the EA sript to see what im talking about. I originally had went into script and changed the "extern lot" to 0.01 and then all the way at the very end of the script i changed those 2 "lot" options to 0.01. Now with all that done, even though i have the ability to chose number of lot in the EA load to chart screen, when back tested if reverts to 0.01 no matter what i put in the lot option in the load to chart screen.

Here is the script. As you see it has the "extern lot" at the top. Also at the bottom i changed to what it shows "if(lot<0.01) lot=0.01". I did this because it originally wouldnt trade at this level a lot. Now i want to be able to chose the lot from the load to chart options menu, so i dont have to re edit every time..
