Yes, I do know that. I have found many solutions for displaying some kinds of S/R levels but I couldnt have found this one Im interested in. I believe I would be able to put this into the code myself but I just need some idea to push me - not sure in this moment how to put this into the code this...

I did the hard way... Below is the code which SHOULD BE capable of doing what I described above...

However, it shows me error during backtest "Array out of Range." Unfortunately, I don't understand the explanation very well... I thought this line would solve it but it did not. (Bars > Number_of_candles)

Any help? (I read what the error means but I dont get it)

Number_of_candles = 15 int PS = Number_of_candles+1; //PS=16

when you reach

if(High[PS] >= High[PS-17] && High[PS] >= High[PS+17])

PS-17 is [-1]

There is no such bar, so you get "array out of range"

Oh! How easy... Thank you very much! when I finish this one, I will upload it here for benefits of others

Tried to put it into the indicator to draw a line on the graph... I cannot figure it out how... again. Anybody? you might see the mistake immediately...

Hello guys,

I have a question about recognizing supports and resistance levels in MQL? My idea is this:

-input int checkbars = X; (in order to make it easy, lets imagine this variable is 21

-if 21st bars´ highs on each side (to the left and to the right on the graph) are above from the certain bar's high, it would draw a horizontal line on that price level which is highest

-Thus, the indicator would be checking from the bar 21 (considering 0 = current unclosed bar)

-by the variable checkbars we could change the sensitivity. Higher value – lower sensitivity and vice versa

-on the picture are the S/R levels. To explain further: the higher line would be where it is, if the “checkbars” would be 21 or less. If it was 22, then the indicator or function would also count in the next large bar penetrating this level. Thus, the line would not be created where it is… Also if we set the checkbars to 5, then the line would be created on the highest high on the visible graph in this picture

I believe it has some sense but I have to admit, that my programming skills finish right here and I have to ask for help - how would you make such an indicator? because of optimalization it is necessary to have the possibility to change the variable "checkbars", if it wasnt, I would just put this into endless conditions if(...) and would not bother you...

Any help much appreciated!

Tick volume is equal to amount of ticks at the unit of time. There is direct correlation between tick volume and real amount of deals. Every change of the price is a result of a real request to perform a deal. Consequently, fewer requests we have, the less price changes we get, and, as a consequence, tick volume is smaller. In this case, when big amount of requests appear on the market, price changes happen more often. Big tick volume appears. Tick volume is an important indicator of trad
