Repaints Hull Turning Points & Concavity Questions For ThinkOrSwim

@Mashume's Hull Moving Average Turning Points and Concavity (2nd Derivatives)

The upper study plots Hull Moving Average with the addition of colored segments representing concavity and turning points: maxima, minima and inflection.

The lower study is a plot of the calculation used in finding the turning points (which is roughly the second derivative of the HMA function), where zero crosses are the inflection points.

######################################################

Upper HMA colors:

Green: Concave Up but HMA decreasing. The 'mood' has changed and the declining trend of the HMA is slowing. Long trades were entered at the turning point
Light Green: Concave up and HMA increasing. Price is increasing, and since the curve is still concave up, it is accelerating upward.
Orange: Concavity is now downward, and though price is still increasing, the rate has slowed, perhaps the mood has become less enthusiastic. We EXIT the trade (long) when this phase starts. Very little additional upward price movement is likely.
Red: Concave down and HMA decreasing. Not good for long trades, but get ready for a turning point to enter long on again.

Upper Label Colors:
these are useful for getting ready to enter a trade, or exit a trade and serve as warnings that a turning point may be reached soon

Green: Concave up and divergence (the distance from the expected HMA value to the actual HMA value is increasing). That is, we're moving away from a 2nd derivative zero crossover.
Yellow: Concave up but the divergence is decreasing (heading toward a 2nd derivative zero crossover); it may soon be time to exit the trade.
Red: Concave down and the absolute value of the divergence is increasing (moving away from crossover)
Pink: Concave down but approaching a zero crossover from below (remember that that is the entry signal, so pink means 'get ready').

Arrows are provided as Buy and Sell and could perhaps be scanned against.

Lower Study:
plot of the divergence from expected HMA values; analogous to the second derivative in that the zero crossovers are of interest, as is the slope of the line. The further from zero, the stronger the curve of the concavity, and the more likely to reach a local minima or maxima in short order.
The lower can give you a preview of when things might be approaching a concavity shift, and how quickly or perhaps decisively they are crossing.

mod note:
@mashume's Hull has a lag because it waits for future bars to close before it REPAINTS the perfect signal. For us, longer-term swing traders, the lag is not a barrier to using @mashume's excellent study. But for scalpers, day traders, and short-swingers, @mashume's Hull might not be an optimal choice.

Thank you @mashume and @MerryDay for your responses.
What would be a good indicator to go along with this to catch those buy signals and then swing it for a few days?

It is traditional to add a support & resistance and volume to swing trades.

Where Day trading is not about indicators, it is about being able to read price action
Swing trading is not about indicators, it is about picking the right stocks.

Thank you for clearing that up for me.

I would like to compare the lagging two-bar label against current strategies that I currently have going. Might you be able to point me in the proper direction? After fiddling, I still cannot get a responsive label. Do you know which historical bars would I need to change or adjust?

Without seeing your script, no one can guess where you went astray.

Post what is not working.

Hi all. I am new to this, I was wondering if someone could help me soften the Hull moving average (top code V4) and at the same time bring it closer to price.
My idea is to modify the code so that from time to time (user selectable) the HMA takes the exact value of the price, at that moment. After that it continues smoothing until the next moment it takes the price again and so on until the final.You experts will say if it is possible. Thanks.-

You could, I suppose do something like take the price at the hour (every hour) and 'shift' the HMA by the difference between the HMA and the HL2 (or whichever price you chose) for the next hour. It would probably be interesting to shift the HMA whenever an indicator registered a high/low support level rather than hour, but hours is easier (in some ways).

Perhaps someone will do this before I get to it, but I'll give it some thought after lunch if I am able.

So I thought this was interesting enough to warrant looking at. Cool idea.

Code:

declare upper;

input HMA_Length = 55;
input minutes_between_adjustments = 30;

def trade_time_s = SecondsFromTime(0000);
def delta_t_s = trade_time_s - trade_time_s[1];

def thirty_min_blocks = trade_time_s % (60 * minutes_between_adjustments);

def HMA = MovingAverage(averageType = AverageType.HULL, data = HL2, length = HMA_Length);
def price_at_halfs =  if thirty_min_blocks < thirty_min_blocks[1] then  HL2 - HMA else price_at_halfs[1];

plot HMA_ADJ = HMA + price_at_halfs;
HMA_ADJ.AssignValueColor(if price_at_halfs > 0 then color.dark_green else if price_at_halfs < 0 then color.dark_red else color.black);

plot adjustment_point = if  thirty_min_blocks < thirty_min_blocks[1] then HMA_ADJ else double.nan;

adjustment_point.setPaintingStrategy(PaintingStrategy.POINTS);
adjustment_point.AssignValueColor(if price_at_halfs > 0 then color.dark_green else if price_at_halfs < 0 then color.dark_red else color.black);
adjustment_point.SetLineWeight(5);

Do with it as you will.

My trading is all about the HMA. I will pull, twist and bend this to see what happens .

Everyone here has been so amazing and so helpful I am ashamed I have not been able to add anything to the catalog of studies here. I am not to bashful to ask for help once again though.

I am trying to sum the value of the MA_max arrows and subtract the sum value of MA_min arrows and show them on a label. I thought it would be pretty simple and I might be able to do it .... but as you can guess, it is out of my league at the moment. Any help would be very much appreciated.

"plot MA_Max = if HMA[-1] < HMA and HMA > HMA[1] then HMA else Double.NaN;"

HMA[-1] is referencing the future value?

Easy way to troubleshoot is to output your variables and check them.

Example:
AddLabel(yes, HMA, color.white);
AddLabel(yes, "HMA_neg_one:" + HMA[-1], color.white);
AddLabel(yes, "HMA_plus_one:" + HMA[1], color.white)

Good luck

Hello Mashume!! I would like to ask if you can recommend any configuration for this strategy, to use in swing trading.-Thank you very much.-

I just write code. ;-)

But seriously, I wouldn't know what timeframes / hold lengths / risk-on level / etc... you are comfortable with. Backtest and decide what works for the assets you're trading and the style you want to trade with.

Happy Trading,

Issues with Alert on HMA Indicator

Good Moring All,
Does anyone see an issue with this script? I cant get the Alert to announce....
I know the program settings are correct as I imported a quick SMA crossover and it sounded fine..
I tried

input price = close;
input Length = 5;

plot HMA = MovingAverage(AverageType.Weighted, price, Length);
HMA.DefineColor("Up", Color.GREEN);
HMA.DefineColor("Down", Color.RED);
HMA.AssignValueColor(if HMA > HMA[1] then HMA.Color("Up") else HMA.Color("Down"));
HMA.SetLineWeight(3);

plot MA_Max = if HMA[-1] < HMA and HMA > HMA[1] then HMA else Double.NaN;
MA_Max.SetDefaultColor(Color.WHITE);
MA_Max.SetPaintingStrategy(PaintingStrategy.POINTS);
MA_Max.SetLineWeight(5);

plot MA_Min = if HMA[-1] > HMA and HMA < HMA[1] then HMA else Double.NaN;
MA_Min.SetDefaultColor(Color.WHITE);
MA_Min.SetPaintingStrategy(PaintingStrategy.POINTS);
MA_Min.SetLineWeight(5);

Alert(MA_MAX, "SELL, SELL, SELL", Alert.Bar, Sound.BELL);
Alert(MA_MIN, "BUY BUY BUY", Alert.Bar, Sound.BELL);

My understanding has always been that scripts which use forward-looking variables such as the Hull Turning Points cannot have alerts.
However, this member seems to have had some luck with using this script:
https://usethinkscript.com/threads/...avity-2nd-derivatives.1803/page-18#post-35731
No idea if it is viable or provides appropriate signals.
If you use it, come back and tell us the results.

Hello all…

I’m looking to see if the labels below can be somehow be converted to scannable conditions. I’ve been tooling around with it but my knowledge of thinkscript language isn’t quite good.

def HMA_MA_Min = if HMA[-1] > HMA and HMA < HMA[1] then HMA else Double.NaN;

Hi,
I love this study. I having trouble trying to figure out how to get the value of the turning points.

I would like to get the value of the last 3 bullish and 3 bearish turning points is that possible?

Bullish turning point = DarkGreen to LightGreen
Bearish Turning Point = Orange to DarkRed
