alternate orders

Eduardo Robson 2008.02.10 16:11

Hello,

Greetings to all.

I would like to know if there is possibility of creating a command to alternate orders. That is, the type of order is never repeated 2 times.

Example: Total orders daily: 5,

1ª order = Bye
2ª order = Sell
3ª order = Bye
4ª order = Sell
5ª order = Bye
.....

I am grateful for anyone who could ajuadar me.

Sincerely,

Eduardo

Here is a way:

 
 
bool BuyOrderNext = true;
 
int start(){
   ...
   ...
   ... decision to trade ... {
      if(BuyOrderNext == True){
         OrderSend( .. buy order ...);
         BuyOrderNext = false;
      }
      else{
         OrderSend( ... sell order ...);
         BuyOrderNext = true;
      }
   }
}

Hello phy,

This command is very interesting.

Meanwhile, I tried to copy and system returned an error message.

I leave the code attached to an evaluation.

Thanks for your great help,

Eduardo

Eduardo, you should look up the definition of pseudocode...

https://en.wikipedia.org/wiki/Pseudocode

My example contains pseudocode.
