EA to calculate lotsize based on a sl .

EA to calculate lotsize based on a sl and able to do a tp1 and tp2 and optional tp3.. once the ea is added i want to drag the sl and tp lines on the chart the ea will calculate the lot size based on the dollar amount i put in by hand so even if i have 1000 and want the lot size based on 500 it will use that number instead. Once the lines are dragged into place i hit execute and it splits the lots to give me 3 if shosen or 2 if chosen or 1 if chosen tp. So if i choose 3 tp and i drag the sl to risk1 percent of 1000 which is 10 dollars if i drag the sl to 10 pips and i choose all three tp it will automatically put in an order for 3 . Tp of about 03 if i choose 2 tp it will split it between 2 or 1 tp will be all on the one tp.it has to be fifo compliant also. If i set 2 percent of 1000 it would auto figure based on where the sl is dragged as i said even if there is 2000 in the account. also .
