Dear Professionals, could you advise... I'm using line drawing in the indicator:

The problem is that when I switch to another timeframe the lines are drawn according to the new parameters, but the old ones are not deleted. What should I add and where should I put it so that when I move to another timeframe the old lines are not drawn? Thanks...
You need to set deinit to delete old lines.
 

Tell me what's wrong:

double order=AccountEquity()/4100;

...

ticket=OrderSend(Symbol(),OP_BUY,NormalizeDouble(order,2),Ask,10,Ask-SL*10*Point,Ask+SL*20*Point, "buy_order",1,0,Green);


it gives out: 2011.03.08 16:35 ScaplerM5 EURUSD,M5: OrderSend error 4051
2011.03.08 16:35 ScaplerM5 EURUSD,M5: invalid amount for OrderSend function

Probably, the lot size is smaller than allowed.

I.e., if the minimum allowable lot is 0.1, but your lot = 0.09....

 

Good evening all!

Can you please tell me if TimeCurrent(); - returns the last known server time, the time of the last quote, or the last arrival of any instrument?

According to my experimental data, it's the second one.

I just want someone to confirm it!

Thanks in advance for the reply!

Actually, it's the current server time.... which was received last...

So, not the time of the last quote for a given currency pair?
 
BBSL:

Yeah.

That's what it says in the help - "last server time". It's not tied to a specific currency.

 
sergeev:

Yes.



So... So I had a question...

I have a need in init(e) to use a function that collects ticks for the current currency...

I've solved it like this - 

double init_array[10];


int init (){

int count = 0;
int time = 0;
int size = ArraySize(init_array); 


time = TimeCurrent();

while (count != size){

if (time != TimeCurrent()){

time = TimeCurrent();

init_array [count] = Ask; 

count = count + 1;

}

}


}

But, if you pay attention to the code and my question, I have a lot of values that will stupidly repeat...

What to do, how to make Expert Advisor react only on new tick arrival for a given instrument.

I have an idea to compare i and i+1, but if two equal ones arrive in a row, we will lose one of the values.

Please assist))

remove while

move the code to start

and parameters 

int count = 0;
int time = 0;

outside

 
sergeev:
remove while


Yes, you can, but in case expert is multicurrency, it won't solve the problem, right?

Still, can we solve this trabble in the inite?)
