Hi Andre, have a look at this!

I just through this together to get something up and running based on your description, but what i’m thinking may not the same as you.

It could help if you elaborate more on the reasoning why you want the rectangles and how you intend to use and interpret them and where.

If you import the .itf file you can dynamically change the variables through the indicator config setting. If you cut/paste you will have to remove the ‘//’ at the beginning of lines 4-9 and save again via [Apply to… xxxxxxx…] button .

defparam drawonlastbaronly = true

////dynamic variables with default values
//current = 1   // boolean, display current month rectangles
//previous = 1  // boolean, display previous month rectangles
//draw1 = 1     // boolean, draw lbk1 rectangle(s)
//draw2 = 1     // boolean, draw lbk2 rectangle(s)
//lbk1 = 20     // integer, lookback 'n' bars
//lbk2 = 40     // integer, lookback 'n' bars

once idx = -1
// entry guard
lbk1 = abs(max(lbk1,1)) // positive, not zero
lbk2 = abs(max(lbk2,1)) // positive, not zero

if month <> month[1] then           // change of month
idx = idx + 1                    // increment the array index
$bar[idx] = barindex             // store bar and highs and lows
$HH1[idx] = highest[lbk1](high)
$HH2[idx] = highest[lbk2](high)
$LL1[idx] = lowest[lbk1](low)
$LL2[idx] = lowest[lbk2](low)

// rgba settings
r = 100
g = 150

if islastbarupdate then
if isset($bar[1]) then
for i = lastset($bar)-1 to lastset($bar) // loop the last two entries

// switch for previous and current
if previous and lastset($bar)-1 = i   or current and lastset($bar) = i  then

// retrieve data from arrays
bar = $bar[i]
HH1 = $HH1[i]
HH2 = $HH2[i]
LL1 = $LL1[i]
LL2 = $LL2[i]

for i = 0 to 1  // loop for lbk1 and lbk2's data

lbk = lbk1-1
HH = HH1
LL = LL1
if i = 1 then
lbk = lbk2-1
HH = HH2
LL = LL2
endif

// switch for draw1 and draw2
if draw1 and i = 0 or draw2 and i = 1 then
x1 = barindex - bar
y1 = HH
x2 = x1+lbk
y2 = LL
endif

drawrectangle(barindex[x1],y1,barindex[x2],y2)bordercolor(r,g,b,0)coloured(r,g,b,a/5)
drawsegment(barindex[x1],((y1-y2)/2)+y2,barindex[x2],((y1-y2)/2)+y2)style(dottedline,1)coloured(0,0,0,a/2)

Hi Andre, took a look at that video, thought the ‘Open Interest’ looked we’ll, interesting but not expecting that to appear any time soon.

Having been inspired, I did another version which should at default be the same as other with reference to the rectangles.

New features are:

To add a third lookback rectangle, if you want to go there 60 !

‘num’ allows more than 1 previous month to be displayed.

‘back’ allow shifting of the blocks back a month at a time to look at previous situations.

‘mnLine’ displays some guidelines on every month and highlights the quarters.

Also a 20 bar look forward box is displayed.

‘text’ allow hiding the text,, encoding 0 = all, 1 = price , 2 month/array data index

Known issues…

using ‘back’ only goes back so far, using more units can get around this if its a deal breaker.

The future quarterly highlight doesn’t show until its current bar.

lookforward box may not be  20 bars, because of divergence between time/bars and market closed.

And doesn’t choose right level as intended at times. Needs work!

I think this type of indicator would be best implemented as just 1 rectangle and then multiple indicators could be added to a chart in a similar way as if you have multiple moving averages.

Arrr we’ll…

Hi Andre, been using this version since a wrote it several days ago , not seen a problem like what you describe and its been running in a chart for at least 12 hours a day over 2 desktop PC at different locations and internet.

Since I have been programming with PRT and ProBuilder  I have not seen this issue but, can’t rule it out 100%.

If the indicator errored in some way I would expect error to be limited to the chart window where indicator added and would only expect it to affect that indicator and not other independant elements of the chart like the price candles, manual drawn objects and other added indicators or the PRT/OS. If a internal error was triggered, I would expect a possible an error message, but not that’s not 100% either

Just to clarify, the prior versions indicator only displayed the rectangles when added to the/a price window and used on the ‘Daily’ timeframe. However, this version tests for ‘Daily’ timeframe and displays error message if on other. Returning back to ‘daily’ removes message. Message displayed, can be disabled via settings if you needed change to other timeframe and remove message. Message won’t re-appear again until enabled again.

My current PRT version is 12.0 – 17.0.7 found under [main menu bar],[Help],[About].

Looking at the code, the use of ‘Array’ and the ‘Anchor’ commands came in on Version 11 maybe Version 11.1, if a remember right. If your version was not compatible I would expect some error message informing you of the situation.

Only thing I can suggest is, if it is the indicator, you would expect repeatedly getting the problem if continue to use.

Recently adding it, and now not using it, my appear to point to it having a problem if you never get it again, but, doesn’t rule out that it could have been a coincidence with some other issue. [prt,java,windows,OS,PC, mac,internet, power spike, too much coffee, working too hard]  etc.

If I were having the problem I would try to identify and eliminate the variables of using it in the situation when error occures and correlate them to isolate down how to trigger error and which/what variable(s) were responsible.

I know it would be better to say it’s this!, but i don’t think were there at the moment , at this time I cannot see any thing in the indicator code, and something happened is a big gap to investigate without gathering more data/information.

Regarding your comments and oservations when error was occurring, chart freezing could related to a loss of data connection and/or the processor doing heavy duty number cruching on something else in the background and not updating.

Memory could have been a issue and a blank screen points possible to the video not being updated. All these could be signs of computer crashing, but why it crashed, we’ll there a good question.

Yes, when a W10 or W11 update is prepared in your PC, it may misbehave for a day (everything is hogged, as it seems).
