I'm hoping an experienced coder can help with this project.

The idea is that a small icon will be placed on the chart every time price crosses a PIP line. These icons will accumulate, and the latest cross will have not only an icon for that cross, but for every other cross on that same price as well. Example shown below. The red icons are past crosses, and the black icons are the total of every cross on that same price. Notice that the latest icons go forward (to the right) on the chart, creating a kind of heatmap S/R line. The more crossings, the longer this line will stretch to the right.

Inputs Wish List:
1. Choice of several different icons (dingbats) (at least 10 choices -- e.g., 6-pointed star, arrows right, arrows left, arrows up, arrows down, diamond, square, hollow circle, solid circle, smiley face, thumbs up, and so on...)
2. Icon color and size selections. Size given in points (pts)
3a. Frequency selection #1: draw an icon drawn at every pip crossed within the lookback TF; at every 5th pip; every 10th pip; every 17th pip; every 29th... and so on. This should be a blank fully customizable setting for any number between 1 and 100.
3b. Frequency selection #2: This requires at least 2 filtering parameters to cross-reference the icon placements. Parameter #1 is Lookback, and #2 is Desired Minimum Frequency. E.g., User chooses 10 days for Lookback, and "30" for Desired Minimum Frequency. Now the indi will only show where the same price has been crossed at least 30 times (and possibly more) over the last 10 days. Both parameters are blank fully customizable settings. This is my preferred method.
4. Lookback setting -- i.e., locating and marking crosses going back -n- days (ex: 100 days worth of data)
5. Older icons will be one color, newest icons will be a different color, just like in the pic. Customizable color selections for each.

That's it. I hope someone likes the idea enough to help code it. Many thanks in advance!

Hi FH...

I have this in my backpack.
Does what you want, on a daily basis (usable on any TF);

Can't remember where i got it from, but there are many similar here in FF.

Thanks Squalou. Glad to have you back.

This indi looks interesting, but it needs some filtering. Let me play with it for a couple of days and get back to you.

How's the Stairstep EA looking, btw?

Here is my code for showing pivot and consolidation points. The easiest way to play around with it is to make a vertical line called "SHIFTLINE" you can drag this around the chart to simulate that being the current bar. You then need a new tick so markets have to be open or you can recompile the indicator to refresh. Also you can run it in strategy tester just set VisualMode = true.

I tried to comment some of the parameters so just open the file if something is confusing.

You've been busy this week!

This looks interesting. I'll try it out once markets re-open.

Let me make sure I understand something. The Start line and the Histo remain fixed on the chart, but we're supposed to move the Shift line back and forth manually. And by doing so the vertical heatmap histo will change shape. Am I getting that right?

Yes the shiftline is a manual control. Just make a vertical line and name it SHIFTLINE. The startline will be NumBars back from the shiftline on a redraw. You can move it around off hours but it won't refresh without refreshing the indicator somehow. There is no way to get an event in an indicator without an incoming tick of data. You can also have no shiftline and it will just work from the current bar.

So far I am using the Market Profile and Fractals only, without Volumes. All other settings are default. Nice job coding a literal interpretation of my original request.

My first question is on the attached pic...

Definitely liking what I see so far.

FWIW, I'm not using the Shiftline, the TDSD, or the Volumes. Not even sure what TDSD stands for, actually. But the Heatmap and Fractals look great together.

Q: Is the current candle part of the calculations? (I don't think so, but if Yes please change to No.)

Mod request1: I'd like to see an option where N bars besides just the current bar can be ignored. For example, if set to "30", then the indi will ignore 31 bars (Current Bar + 30 more besides.)

This is code I have used for a while now. I just pulled all the work I had to try to interpret the Histogram and make horizontal lines. I saw your request a while ago but only recently had enough vouches to post here.

Funny I looked at you picture for a while since your 2 lines look like trendlines. I was like what does he mean vertical lines.


Here is the setting for that


//This is where the histogram is divided (1.0 is the average).
extern double HistogramThreshold = 1.5;

TDST is tom demarko sequential. The idea is to find the end of runs so it count seqential closes +/- the close 4 bars previous. I don't use it for OBOS but if you get a run in a direction and it consolidates for a few bars that makes a good pivot point. The TDST histo attempts to find these points. I figured you would toss it since it doesn't relate directly to your style of trading. In my study of price action it has been useful to observe it.

For your question. It should not use the current bar. It actually should not use the most recent FractalLookBack number of bars. Since this is also a look forward and I wanted to be sure this code is simulator safe I try to make sure it can't cheat.

In a way you could set this high like 30 and get the results you are looking for in your mod request. But it is not clean and would change the fractal weighting behavior.

You mod request is for just an automatically moving shift point correct? I can add that but I am currently catching up on my life after a vacation so you might have to wait a bit.

Totally cool that you used my indicator in your SSBO posts even though you got flamed for it (double cool).

Yeah, some idiot who doesn't take the time to read my posts accused me of holding back some super secret indicator and just post pics of it because I want to entice Factory members into buying it from me on the sly. LOL The stuff some people come up with, my goodness. I don't know if I should laugh or cry some times. The paranoid fantasies of some people, I swear...

Sorry about the confusion on the 2 white lines. I didn't see the trendline correlation before, but I do now that you pointed it out. Funny stuff. No, what I was trying to find out was whether the distance between the lines correlated to a specific number of back bars getting crossed. This would be for the heatmap histo. For the fractal histo, it might translate to how many "^" fractals are being counted.

For example, for the heatmap could you make it so that the baseline (the standard space between the 2 vertical lines) is 25 bars.

Or for the fractal histo, the baseline might be 35.

Hit rates that fall under these values are the shorter red lines. Hit rates equal to (or larger) make the lines turn green and grow longer.

See where I am going with this? I would like these 2 features to have a custom input where the hit rates can be user defined. This would now become a static ratio. Just a fixed number chosen by the user. The actual on-chart distance between the 2 lines doesn't change. What fluctuates is how the hit rates react to the base line. A higher number (e.g., 50 instead of 25) would cause the histo to give back a different reading as it compacts the data into the horizontal lines.

As for ignoring recent bars, I would like custom input where I get to choose how many recent bars to ignore -- e.g., 30. This would mean that the data from these bars does not figure into the histos at all. (In reality it would be 31 bars, since the current bar is never counted.)

What about it? Are these kinds of mods even possible?

Anything is possible.

The thing too understand is that these values are not bars that is just how they are projected on the screen. The underlying values would fluctuate considerably depending on the type of histo and other settings like UseVolume etc.

That being said it can easily have an absolute option, it just will require a bit of trial and error for you to use it properly. You could need a value of 10000 for one setting and 5 for another if that makes sense. What do you mean by having it grow when it is green? The value is the value. Nothing changes around the threshold except the color.


I am attaching a new indicator with a MovingShift property that will let you offset the start point. BUYER BEWARE. It is up to you to observe and understand how many bars this uses. 30 31 I don't know. I do not have the time to precisely debug and document exact bar usage behavior under all settings. I only know that I am pretty ie 99% sure this is simulator safe.

Let's take a step back, please. You obviously know more about coding than I do, and I think you're over-thinking this a bit. I hope this pic helps simplify things.

Don't have anything extra for now, just what the pic shows...

I wasn't overthinking. You were overly confusing.

Ok I didn't see your second picture post. It shows what I thought you meant but that doesn't seem like it would work since the values are normalized to fit on the screen. You can't change the size of the line distance and display it the same without potentially having the larger lines blow out the screen.

Your recent post is what I thought you meant to do with it. It can have an absolute threshold option like I said. Was going to do it quickly but I realized it would need a separate setting for each histo to be useful so I will have to get it done tomorrow. Lets start with that and see how it works.

So on your "actual box on the chart" comment in your last post. Are you saying you want to actually draw the box that gets used in the histo? I did not read that into your first request but it would be a good idea. I have often wanted to have it only use a virtual box that is +- X amount of pips around the current price but just drawing the box like the shiftline would be nicer. This is not super easy (why I haven't done it already) so I will look into it when I can.

Sorry for any confusion, but it looks like we're on the same page now.

~Yes, an actual box is preferred. Look up member Hanover, he has quite a few custom indis with interesting chart artifacts, including boxes that can be made either hollow (as in my pic), or solid. Give the box custom color and line thickness selections. With the right settings we can make it nearly invisible, but still showing just enough for a quick visual reference.

~RE scaling the horizontal histo lines: First, I don't think the values index over just the last 1000 bars is going to be that great. And second, if it proves to be so, then all you (the User) have to do is go back to the inputs and increase the baseline value until the lines reduce to something more functional. Just keep moving the value up by 10 or 20 points until you get back histo bars that fit your screen. Easy.
