Is there a way to code so when the dots change color?

Iv changed the Hull 9.

Hi   just came across this thead and im interested in incorporating the Hull 13 into one of my existing algos.   The logic is along the lines of “if Hull is on trend then” I can see how to get the hull, I can see it on my chart, is it possible to get the algo to know if its on or off trend as part of its logic?   cheers

Goodmorning Nonetheless, Thank you very much for sharing the trading concept  !     I can imagine you want a trading machine instead of looking yourself to the 2 minutes chart for the whole day !!

1. First I assume that the Hull code you have defined/coded is the same as the standard Hull average in PRT version 11  (indicator1 = HullAverage[13](medianPrice)  (not sure if medianPrice meets your Typical price, in the Hull indicator you can select your desired calculation of the bars open close high low.)

2.  The basic rule c1 = HULL > HULL[1] and HULL[1]<HULL[2]   generates too many false and too late trade actions when the Hull averages reverses in what I call sloppy trade session (no trend), which happen quit often.  3.  As a possible way to avoid those wrong zig zag trading actions, you could make something for opening Long buy, like  c1 = HULL[2] = lowest[5](Hull)  and close < Hull[1] + 2/1000 * close     this rule is quite arbitrary and needs to be tested: the idea behind this rule is GO LONG when the Hull13 average  of 2 bars back is the lowest of the last 5 bars Hull13 average and the Close is not run away, not being higher as 0,2% of the pre-last Hull average.   4. The long HULL34 might add value, when defined as HULL34 slope, which is defined as simple as Hull34 – Hull34[4], whereby 4 arbitrary is When the short HULL is increasing, you would expect the slope to increase ; the slope can be negative, (when the Hull34 is still moving down), but less steep/negative  then previously. The slope could also be positive and become more positive. An additional buy long condition can then be added  c2 = SlopeHull34 > SlopeHull34[1] The slope indicator could be added as an indicator, to better see how the slope behave at different price movements.   5.  Additionally  your condition implemented :  “For example, if the 13 reversed but the 34 maintained a strong trend I would close but not reverse my position, just wait for them both to be moving the same way again.”, that would be a third buying condition. Maybe you can define the STRENGTH of the trend  with defining the minimum steepness of the HULL34, comparing the current HULL with the HULL e.g. 3 bars back . Buy long c3 = average[4](Hull34) – average[4](Hull34)[3] >  0,5 %  (arbitrary)     (This buy condition prevents reversing into a long position with a strong negative trend) Reverse the conditions for open short positions. Be aware that Condition 2 and 3 might give more trend following opening positions, but also prevents aggressive  buying/short selling when the short HULL conditions are true.   Hopes it helps you with more ideas to work out an algorithm for your trading, and let the machine make profit for you. I will in a later stadium test your concept myself in a strategy, hopefully it gives some nice results.  If you have further questions, let me know.   PS: You might also try to LOG this average: LOG(Hull34), it might give faster the turnaround signal (not tested myself) PS 2 You may also like the Heiki Ashi Bar chart presentation, which can standard be selected as an options in the graphs, which in my opinion better presents the trend. I added an average Heiki Ashi indicator, with average period of 6, which could be added to the graph.

//Heiki Ashi in graph, calculation averaged with Hap bars

Once Hap = 6 //Heiki Ashi Average Period

if barindex < 2 then
HOpen = (open+close)/2
else
HOpen = 0.50 * (hOpen[1]+hClose[1])
endif
HClose = 0.25 * (Open+Close+Low+High)
AvHA = average[Hap]((HOpen+High+Low+Hclose)/4)


if AvHa < AvHa[1] then
ar=128
ag=128
ab=128
else
ar=48
ag=84
ab=150
endif


return   AvHA coloured(ar,ag,ab) style(Line, 4) as "Av Heikin Ashi"

Log is a mathematical formula,  and  stands for Logarithm  https://en.wikipedia.org/wiki/Logarithm In PRT it can be used by typing LOG before e.g. HULL34.   LOG(HULL34) Do not put too much worth on it, but I think the log average crossing is smoother and earlier than the normal average crossing, so it could help with eliminating sloppy trades.  But as said, its need thoroughly testing with HULL averages, regrettable I do not have statistical proof

The Heiki Ashi calculation as I presented above was NOT correct for the Heiki Ashi High and Heiki Ashi Low, sorry,  below the correct calculation of the (average) Heiki Ashi  for your information.  

//Heikin Ashi candlestick definition according Investopedia
Once Period = 3

if barindex < 2 then
HOpen = open
HClose = close
HHigh = high
HLow = low
else
HOpen = 0.50 * (hOpen[1]+hClose[1])
HHigh = max(HOpen,max(high,Close))
HLow = min(HOpen,min(low,Close))
HClose = 0.25 * (Open+Close+Low+High)
endif

AvHA = average[Period]((HOpen+High+Low+Hclose)/4)
//if Hclose > HOpen then
if AvHA < AvHA[1] then
r = 128 //51
g = 128 //125
b = 128 //79
else
r = 48 //192
g = 84 //0
b = 150 //0
endif
