Can someone help me with the code (Random Lot Size)

New comment
 

Good Day everyone,

Can someone help me with the MQL4 code setup of random lot size.
I want to have several input for the Lot size.

Lot size A = 0.01
Lot size B = 0.02
 Lot size C = 0.03
Lot size D = 0.04
 Lot size E = 0.05

And EA will choose Randomly for this lot size number when opening the trade.


input double lot     = 0.01;  // lot
input int slippage   = 8;    // max slippage
datetime tlast;
int OnInit()
{
   tlast = INT_MAX;
   return INIT_SUCCEEDED;
}
void OnTick()
{
    if(Time[0] > tlast)
    {
        if(Open[1] > Close[1])
            bool res = OrderSend(_Symbol, OP_SELL, lot, Bid, slippage, 0, 0);
        else
        if(Open[1] < Close[1])
            bool res = OrderSend(_Symbol, OP_BUY, lot, Ask, slippage, 0, 0);
    }
    tlast = Time[0];
