mila.com:

Thank you.

Here it is

...

Just to clarify.

I want to put the arrow up if the indicator line has crossed level 20, on M1 period, and the indicator line is directed up, above level 50, on M5 period.

Let's see how to get the values from the higher timeframe, being on the lower one:

Thanks, it worked )

In the Expert Advisor, when calling the indicator, I just need to specify the number of the desired timeframe, while the indicator "dances" with the shift. Where can I read more about it?

I have not read it anywhere - I have no idea.

Imagine this: you cycle through the bars on M1. You take indicator values from the bar number, to which cycle index i is referenced.

	i+8	i+7	i+6	i+5	i+4	i+3	i+2	i+1	i
M1	09:52	09:53	09:54	09:55	09:56	09:57	09:58	09:59	10:00
M5	09:50	09:50	09:50	09:55	09:55	09:55	09:55	09:55	10:00
	i+2	i+2	i+2	i+1	i+1	i+1	i+1	i+1	i

In the table in the header at the top the cycle index M1, below it is the value of the bar time to which the M1 index refers

At the very bottom the cycle index M5, above it is the value of the bar time to which the M5 index refers

When you pass the index value from the current timeframe, at which the cycle starts, into the iCustom() function, you get the values of the indicator from the older timeframe according to the index. But the index does not refer to the necessary bar, as it can be seen in the table.

And this should be done in expert advisors as well, otherwise - you're not taking values from the expected bar and think that you've got it correct. Well, you got it right, but not from the wrong bar. This must be known and taken into account.

I.e., at multitime data reception it is necessary to rely on time, and recalculate it to the bar number at the required timeframe.

Artyom, please help me too, I have problems with indicators.

I need to find these constructions and put arrows on them. The functions in the Expert Advisor work and are simple to connect, well, it's understandable - they only need current values, but how to transfer them to the indicator, to draw the coincidence on the history...?

The arrows should be drawn on a candlestick, as soon as the High[1] and Low[1] coincide.

There should be a different logic for different patterns, because not all of them are the same. And for one and the same pattern, the logic should be written differently by different programmers.

And what exactly, which pattern do you want to determine?

Let's start with this.

And what exactly, which pattern do you want to define?

Let's start with this one.

I have attached a picture.

The condition: fractal "3" is higher than fractal "2" and fractal "1" is higher than "2" -FrDn3 > FrDn2&& FrDn2< FrDn1 We look at the candles, the fractals are already formed and wait for the confirmation of the candlestick pattern,

and if there are"3" increasing in a row - buy (arrow) -GetBearBull(dSymbol,0,3)==1(1 - buy)

For selling, it is vice versa.

It's easy to put it in an Expert Advisor, but in an indicator ...

I have attached the picture.

Required condition: fractal "3" is higher than fractal "2" and fractal "1" is higher than "2" -FrDn3 > FrDn2&& FrDn2< FrDn1 We look at the candlestick, the fractals have already been formed and wait for the confirmation of the candlestick pattern,

and if there are"3" rising ones in a row - buy (arrow) -GetBearBull(dSymbol,0,3)==1(1 - buy)

For selling, it is vice versa.

It's easy to put it in an Expert Advisor, but in an indicator...

In the indicator it is vice versa - if you start search in the depth of history, in the indicator - from its beginning. Look for the left fractal first, then the middle one, then the right one.

Manage the flags.

Flag = false
Found left fractal - flag true
Find the middle fractal, if it is higher than the left one, then flag false; if below, go to step 4
Find right fractal, if it is lower than the average - flag false, if higher - go to step 5
All fractals are found and the flag is set - look for three bars in a row with the same flags.

Artyom Trishkin:

In the indicator, the logic is the opposite - if in the EA you start searching deep into the history, then in the indicator you start from the beginning of the history. Look for the left fractal first, then the middle one, then the right one.

Manage the flags.

Flag = false
We have found the left fractal - let's set the flag true
Find the middle fractal, if it is higher than the left one, then flag false; if below, go to step 4
Right fractal found, if it is lower than average - flag false, if higher - go to step 5.
All fractals are found and the flag is set - look for three bars in a row with the same flags.

I'm asking to show the ready variant. I may see it once and the questions will fall away, but now I have a thousand of them and cannot decide.

What to do with all this in an indicator - I have no idea(

Vitaly Muzichenko:

If I could, then no questions, I understand the logic, but I cannot implement it in the code, so please show me a ready variant, I will see it once and the questions will disappear in the future, but now there are thousands of them and I cannot solve them myself.

Do you need a function that returns a fractal bar number by its number?

You need a function that returns the presence of a fractal on the required bar (cycle index+3)
