Power of Three (PO3)

[michelz]

Hi everyone,

I am looking for a free / paid "Power of Three" (PO3) indicator that can be used with NT8.

It should be similar to the Trading View "HTF Power of Three" (by toodegrees) indicator which focuses on.

I would love to know if there is a "Power of Three" NT8 indicator out there OR worst-case scenario if it can be coded?

Many thanks,
Michel

I do not know of an indicator that looks this cute, but this one gives the same info:

Amazing. By the way, the candle displayed within my screenshot is a 4H candle. Thanks!

[MiCe1999]

Ah, higher time frames is what I should be looking at more often. You can use 240 minutes for the period to get 4H candle, however if you're going as big as 4H - volume profile is probably better to look at. I think this type of indicator could use one or two preceding candles as well.

[rockmanx00]

I attempted to make one too. You can change the colors or the wicks, outline for Up/Down candles, the fill color of those candles, and the ability to choose a bar type and a period. You can also choose not to display the value text on the side....


*Edit*
Added Displays to show the Bar type and period above, and a timer for the higher time frame below. There are also boolean you can uncheck if you don't want them displayed, but are on by default.

Changed some of the formatting so the text and HTF candle centers nicely. Also moved the Open and Low texts to the left side of the candle so they no longer overlap each other.

Fixed more centering issues.

Fixed overlapping issue when displaying price. I didn't check to see it worked with green candles, so I fixed some of the logic and it works now.

Fixed some Properties window formatting and descriptions.

Added a check to ensure that the secondary is a Higher time frame.
The Secondary time frame can be either "Second", "Minute" or "Day" time frames.
If the Secondary time frame chosen is lower than the Primary time frame, or the Primary time frame is not either "Second", "Minute" or "Day" time frames, the indicator will default to the Primary data series data.

Thanks for sharing. Clean code, AI has still much to learn.. Have you thought of adding a countdown timer?

[rockmanx00]

I haven't thought of that. I could look into figuring out how to add that. I suppose if I were to add that, I could add the bar type and period above the candle, and place the time below so you know what higher time frame candle you are using and how much time for that particular time frame is left...Good idea.

[furman87]

Not exactly the same thing, but I wrote an indicator that overlays the range of higher timeframe candles over the current price. Candle bodies are shown in color, the wicks are shown in gray. In this example, these are 15 minute candles overlaid on a 1 minute chart.

[rockmanx00]

Nice. I bought something that almost does the same thing. I think it didn't quite overlay as nicely though, was off slightly so I never used it. Pretty sure I paid about $100 or so for it. Good job.

Awesome. Would you mind explaining if you are running the timer on UI thread so it updates outside of onbarupdate interval? Wouldn't it also force refresh of the whole chart and slow down NT? I think I've seen similar construct to speed up chart refresh.

I could be wrong, but I remember having issue with using system time (now) is that it could be out of sync with bar time. I think getting time from Times[0][0] may be more accurate. Or, compare Times[0][0] to system time, from time to time, and calculate clock drift.

[rockmanx00]

For the timer, I pretty much copied logic from the bar timer that came with ninjatrader so if that doesn't slow things down for you, this shouldn't either. It does force refresh and I haven't noticed any slow downs on my end. Also, as you can see, I've been updating it a lot. I've been using it and noticed small things here and there that bug me about it, so I tend to upgrade it frequently. If you notice anything buggy about it, please feel free to let me know so I get work on it. I've tried to set the HTF bar to a 38 minute bar, and that still works.

Thanks again. I figured out how to get our candle to draw where it starts on the primary. It's probably useful for short time frames only.

private int GetCurrentHTFStartBarIndex()
{

  
    // add return if secondary bar still the same
  
    // Start from most recent bar and walk forward in time
    int currentBar = 0; // our index
    
    // Get HTF time - using index 1 since bars have close timestamp
    long htfTicks = Times[1][1].Ticks;
    //Print($"HTF Time: {Times[1][1]}");
    
    //Print($"Starting search from primary bar: {currentBar+1}");
    
    // Walk backward until we find the bar belonging to previous HTF period
