Questions from Beginners MQL5 MT5 MetaTrader 5 - page 701

[Aleksey Vyazmikin]

Vitalie Postolache:

Why all? Complete information for 100 bars at a time (of course, you can specify fewer or more bars). Handy when you need more than just High.

Well, if it's an indicator ... If it's an indicator and if it's an EA, then at every tick to update the array (or overwrite at a new bar) - what's the idea, it's just not clear...

Vitaly Muzichenko:

OK, you have solution for current symbol, I have multisymbols.

I'm trying to re-do the indicator, it has multitimescale - but I'm confused by the calculation of time....

Renat Akhtyamov:

Got this.

At first, it's a bit squirmy. However, rewriting from MT4 is no problem.

I just hate that I have to waste my time on something that has already been done... You don't understand some things right away, it's not so easy.

Here's how to understand - the indicator draws on one instrument, but does not want to draw on another... There are no errors in log...

How do you understand - the indicator draws on one instrument, but does not want to on the other... and there are no errors in the log...

without a code snippet we can't help either

The line from a four

int limit=((TimeFrames*60)/(_Period*60));

is the same as a five, or am I missing something?

int limit=((PeriodSeconds(TimeFrames)/60)/(_Period*60));

TimeFrames - can be any.

int limit=((PeriodSeconds(TimeFrames)/60)/(_Period*60));

TimeFrames can be anything.

maybe it would be better to learn something from this opera?

It's not really about that, or I haven't found a solution...

I can't figure it out - it occasionally swears that division by zero in d1 , but is that possible?

         int limit=((TimeFrames*60)/(_Period*60));
         double d1=(delta_price_high-center_line_point)/(limit/2);

Apparently it is possible if the current TF and the estimated one are the same...
