Can you tell me - does the for inside the for(s) work?

It works. All the other operators even work.

Thank you!
 
Greetings, please provide a code fragment for an Expert Advisor which uses an indicator signal for entry, which creates arrows instead of a line (i.e. the indicator style is defined as SetIndexStyle(0, DRAW_ARROW, EMPTY, 3)). I want the down arrow to sell, and the up arrow to buy. I failed using standard methods for some reason(
 

Can you tell me how to change the rsi period (default is 14)?

Thank you

Guys, can you point me in the direction of registration so I can use OPLI online and get my username and password?

 
See, I got the time by the function 
ObjectGet("qwerty",OBJPROP_TIME2);
I get 1323452400. As I understand the time is in seconds, so if I subtract 600 from this time, the new location will be 10 bars back on the 5 minute chart, but in fact the new coordinate has moved only 1 bar, why is this happening? And for the shift to be 10 bars you have to subtract about 3000, where is the logic here?
 

Can you tell me why I can't print variables, not even 0 pops up.

The lot controller of the respected voix_kas. Slightly reworked by me.

double GetLot(int FastPeriodMA,int SlowPeriodMA) {
int i;
static double Lot = 0;
static double PrevBalance = 0;
static double BalanceOld[0];
static double BalanceNew[0];
if (NormalizeDouble(PrevBalance - AccountBalance(), 2) != 0) {
ArrayResize(BalanceNew, ArraySize(BalanceOld) + 1);
for (i = 0; i <= ArraySize(BalanceOld) - 1; i++)
BalanceNew[i] = BalanceOld[i];
BalanceNew[ArraySize(BalanceOld)] = AccountBalance();
ArrayResize(BalanceOld, ArraySize(BalanceOld) + 1);
ArrayCopy(BalanceOld, BalanceNew);
PrevBalance = AccountBalance();

if (ArraySize(BalanceNew) > SlowPeriodMA) {
double FastMA = 0, SlowMA = 0;
for (i = ArraySize(BalanceNew) - FastPeriodMA; i <= ArraySize(BalanceNew) - 1; i++)
FastMA += BalanceNew[i];
FastMA /= FastPeriodMA;
for (i = ArraySize(BalanceNew) - SlowPeriodMA; i <= ArraySize(BalanceNew) - 1; i++)
SlowMA += BalanceNew[i];
SlowMA /= SlowPeriodMA;
if (FastMA > SlowMA){ Lot = 5;Print(" FastMA ",FastMA,"; SlowMA= ",SlowMA); } 
else Lot = 0.01;
}
}
if (Lot < MarketInfo(Symbol(), MODE_MINLOT)) Lot = MarketInfo(Symbol(), MODE_MINLOT);
else if (Lot > MarketInfo(Symbol(), MODE_MAXLOT)) Lot = MarketInfo(Symbol(), MODE_MAXLOT);
return (Lot);
}

And on every tick the size of arrays increases?

Maybe it would be easier to create a balance indicator. And in Expert Advisors one would address to it.

You can, but the Expert Advisor works slower in this case. And with the output on the screen also nonsense turns out, it draws ONLY when the deal is closed, and how to make it exist as a continuous line of balance, I do not understand, can someone tell?
