Heikin-Ashi

[shali27]

It would be really nice if there were a choice in the chart type drop down box for Heikin-Ashi, rather than having to go into Indicators (and technically, it is a chart type rather than an indicator). I like to switch between this and regular candlesticks, and it's so much easier when it's right there.

Hello shali27,

Thank you for your suggestion.

With NinjaTrader 7 we will be adding additional chart styles which can be accessed from the chart, of which HeikenAshi will be one. Please see the following link.

Hello
Looking for Heikin Ashi indicators, I found the attached Ninjascript as well as this post on Ninja forum.
Now I wonder if I can use this indicator for a simple strategy (for istance, enter long after 3 bearish candles and 3 bull candles). Although I have a limited skill with Ninja Script, I feel I could implement it by myself if I only knew how I identify/initialize the OHLC (Open-High-Low-Close) values of a Heikin Ashi candle.
Can you help me here ?

Hello fliesen,

Thank you for your post.

The HeikenAshiSmoothed would be accessed in the following manner for an up bar:

			if(HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).Close[0] >
				HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).Open[0])
			{
				// Do something.
			}

Very helpful, thank you.
I could compile this "HA" code with no error enabling the strategy with 1 minute timeframe, however I got no alert in the last hour - what is surely unrealistic.
(The strategy search for a retracement, then gives an alert + sets a marker for eventual reversal).
What is wrong with it ?

Furthermore: is it possible to change the neutral outline of the normal candles to green or red, or give them a whatsoever evidence of their bullish or bearish nature ?

[NinjaTrader_PatrickH]

Hello fliesen,

Thank you for your response.

You can use CandleOutlineColor or the outline of the bars to indicate bullish or bearish signals: http://www.ninjatrader.com/support/h...tlinecolor.htm

I will test your strategy on my end and follow up when I have further details.

Hello fliesen,

Thank you for your response.

Comment out the following lines at the beginning of the Initialize() method:

//			Variable40 = Math.Round(Volume[0]);
//			if  (Instrument.MasterInstrument.InstrumentType  !=  InstrumentType.Future)
//            {Variable40 = Math.Round(Volume[0]/1000000);}
//			if (Variable40 < 1 || ADX(14)[0] < 15) return;

Then change the Close and Open of the HeikenAshiSmoothed to HAOpen and HAClose:

			if (HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAClose[1] <
				HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAOpen[1] && HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAClose[2] <
				HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAOpen[2] && HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAClose[0] >
				HeikenAshiSmoothed(0.7, HAMA.SMA, HAMA.SMMA, 1, 2).HAOpen[0])

Perfect, the code now works pretty fine, although some small inconsistencies rarely occur, as for istance the 3 opposite alerts in the same instant of the attachment (can this depend upon the lack of volume v=0 ?) and the fact that NOT EVERY reversal and/or exit warning are signalized in the alert window (even when all internal and external conditions are triggered). May it be that Ninja loses some data at some moments ?
Otherwise everything is ok, many thanks
As to the CandleOutlineColor function, I may implement NinjaScript in a strategy, but how is it in a chart indicator like the HeikinAshiSmoothed_NT70.zip ? Can't I do anything from Parameters/Data/Visual/Plots of a normal indicators window ?

[NinjaTrader_PatrickH]

Hello fliesen,

Thank you for your response.

The two Close alerts have the same condition to alert:
HAClose < HaOpen.

There is no option in the Indicators menu to change the CandleOutlineColor.

[fliesen]

1) ok
2) Then, what is the CandleOutlineColor function to add to ?

[NinjaTrader_PatrickH]

Hello fliesen,

Thank you for your response.

CandleOutlineColor is a function in NinjaSCript to color the bars outline: http://www.ninjatrader.com/support/h...tlinecolor.htm

This would be the same as changing it through the Data Series menu of your chart.

[fliesen]

I know this.
I suppose I must write something like

if close > open, then CandleOutlineColor = Color.Blue
if close < open, then CandleOutlineColor = Color.Red

but this isn't a strategy, just a chart, therefore:
to which script must I add it ?

[NinjaTrader_PatrickH]

Hello fliesen,

Thank you for your response.

It would have to be in a script, such as a custom indicator.

[fliesen]

ok Patrick. Thank you

[fliesen]

Excuse me Patrick
I realize that this strategy, just after its enabling, gives me many signals, but very strangely, these signals become fewer and fewer with the day progress, till when they practically disappear with no alert at all. In other words, the strategy seems to work only for a few minutes, what makes it useless.
I am not sure how the HAMA or the HeikenAshiSmoothed is being calculated but I suspect that those values are being smoothed or being calculated over time, producing less variations which is reducing your signal frequency.
If so, how may I avoid this ?
Thnx for any help.

• PS: Variable16 is used just to identify when I should have entered a position (HeikinAshi+ -> 1 or HeikinAshi- -> -1) or closed it (opposite alert -> 0).
