Helping create an ea.

[Theodor Girtan]

Hi guys,i'm looking into making a simple martingale ea but i think i encountered a dead end.

So,the function send_order buy/sell should do the thing it intends to do.I appeal and  it should open a new sell/buy order with the volume increased by the lot_multiplicator but it says "'volume1' - undeclared identifier"

Also,if someone could enlighten me please,what is  the code that after a certain number of pips, a new market order would occur.(this is the biggest issue).

#property copyright "Domnul T"
#property link      "www.primumilion.com"
#property version   "1.00"
#property strict

input double volume;
input double lot_multiplicator;
input int pips;
void OnTick()
  { double volume1=volume;
if(OrdersTotal()==0)
OrderSend(NULL,OP_SELL,volume,Bid,5,0,0);}


void send_order_buy()
{
 double volume1=volume1*lot_multiplicator;
OrderSend(NULL,OP_SELL,volume,Ask,5,0,0);}

void send_order_sell()
{
 double volume1=volume1*lot_multiplicator;
OrderSend(NULL,OP_SELL,volume,Ask,5,0,0);}

Martingale, guaranteed to blow your account eventually. If it's not profitable without, it is definitely not profitable with.

"'volume1' - undeclared identifier"

This is because you use a #property strict

You have to declare volume1 at a global level

 double volume1 =0.0;

void send_order_buy()
{
 volume1=volume1*lot_multiplicator;
OrderSend(NULL,OP_SELL,volume,Ask,5,0,0);}
