Thank you... What a country of the Soviets! Unfortunately, I'm not really burning with the desire to thoroughly study MQL4. At this stage it is of narrow applied interest, i.e. purely for one particular Expert Advisor. I know I don't need a manual, but I want professionals to help me, even absentee tutors are available. Well, we will do it ourselves. But it's a pity about the time.

The only dinosaur left is Igor Kim. And he, in my opinion, has got tired of us ignoramuses. It is a pity...

Why? There's still some...

Why, there's a little more...

Yes, thank you. I also know you from Kim's thread. In recent years the branch has become heavily littered, unfortunately (IMHO).

I dare not address the respected and even revered directly (yet...), but: "A" has already been said...

 

Hello,

Seems to be fine, but it won't show low[1] .

Hello,

It seems to be ok, but it won't show low[1] .



Doesn't it confuse you if it's outside the array?

It's right here:

for(int j=7;j>=0;j--){
       high[j]  = high[j-1];
       low[j]   = low[j-1];
       timeh[j] = timeh[j-1];
       timel[j] = timel[j-1];
     }

Besides, "doesn't want to show" there everything, not just low[1].

 
evillive:

Not confused by going outside the array?

Right there:

I don't get it!?

This loop is only for moving the result.

Then if there's a condition, it'll be the first one again.

The loop accesses non-existent array elements, no matter what it's used for. That's not good.

Suggestions-how to fix it?
