At incoming of new quotes, the start() function of the attached experts and custom indicators will be executed. If the start() function launched at the preceding quote was running when a new quote came, the new quote will be skipped by the expert. All new quotes income while the program was being executed are skipped by the program until the current execution of the start() function has been completed. After that, the start() function will be run only when a successive new quote incomes. For custom indicators, the start() function will be launched for recalculation after the current chart symbol or timeframe has been changed independently on new quotes incoming. The start() function will not be run when the expert properties window is open. The latter cannot be opened during the expert execution.

The question is how do you check to make sure that you are working with the latest tick ?

I came up with this little check but i cant tell if it works or not....

the first thing you do after start() is set the Bid and Ask
PHP Code
int start() {
   //Check to make sure our ticks match
     double TickBid = Bid;
     double TickAsk = Ask;
Then everytime you RefreshRates if there is a change you go back to start.
PHP Code
RefreshRates();if (Bid != TickBid || Ask != TickAsk)start();
The goal is to not execute any orders if there is change in the price... I figured that with this you can avoid requotes and eliminate other strange errors.... Let me know your thoughts....

Also does anyone know how to figure out how long your EA takes to complete once it has been called..
Keep it simple stoopid....

Yeah, I think that could work.
To measure execution time, try something like this:
Inserted Code
int start()
{
     int tickStart = GetTickCount();
//----
// ...


//----
    Print("EA calculation took "+(GetTickCount()-tickStart)+" milliseconds.");

}

Here is my super fancy way to avoid requotes without using slippage...

Basically if there is a change in price while your EA is being executed. It forces it to start over. . . very simple yet usefull tool in EA's that scalp ( you will be under the radar with your broker now) or EA's that require long calculations.

It has already helped my scalper system avoid two requotes tonite...

Making MT4 work for U..... enjoy

PHP Code
 // Internal Variable
int Restarts;

int start() {
   // Ticks 
   int tickStart = GetTickCount();
   //Check to make sure our pricing has not changed
   TickBid = Bid;
   TickAsk = Ask;


// Put this 1 line before you use any "order function" OrderSend() OrderModify() ect...

RefreshRates();if (Bid != TickBid || Ask != TickAsk){start();Restarts++;}


// And for your last 4 lines of code in the start() ...

Print("EA calculation took "+(GetTickCount()-tickStart)+" milliseconds. With "+Restarts+" Restarts...");
Restarts = 0;
return (0);
}
Keep it simple stoopid....

this is useless, lol. just update the rates before you send any orders, thats all. you don't even need to do it if you are not using some fancy looping for minutes..

But if your calculations are based on the tick that triggered the EA. then that tick changes in the middle of the calculation you arent going to want to send that order without recalculating... Its for scalper systems.
