Heiken Ashi

[arilano]

Hi

i am looking at using the heiken ashi indicator but my programming is missing the mark a bit...

basically id like to execute an order if the last bar was green

i tried this but it didnt work

if (HeikenAshiCustom().HAOpen[0] < HeikenAshiCustom().HAClose[0])
{

do something
}

maybe you can use a bar colour property but i tried to just do open greater than but didnt execute the "do something"


any help would be greatly appreciated

Thanks in advance

Logic wise that looks fine but I am not familiar with indicator you reference. You would need to check to make sure there are values returned by this indicator.

yeah i thought so but i dont really understand the indicator that well myself its the Hieken ashi modified one available from the sharing indicators page. It looks very useful but im not sure how to return the colour of the last superimposed bar

If anyone out there is familiar I would appreciate any help

i could probably write some functions but im not sure what to access

Thanks

Just throwing out ideas, you could store the color of the last bar in a variable and just call that variable to get its color in the future.

[arilano]

yeah that sounds like a simple solution (its been a few years since i did my programming course so im a "little" rusty haha) would i have to create initialize and set the variable in the indicator script?

ill have a go this morning

thanks for the suggestion

You would make it just like you make any other variable. You can look through other indicators to get an idea of how they make variables and just mimic them.

thanks for the advice im a little rusty

ive created a variable called lastBarColor in the variables of the indicator and initialised it to empty, thats fine if i do a simple if condition as below in my strategy

if (myHeikenAshi().lastBarColor == Color.Empty)
EnterLong();


this works and the longs are entered

i have narrowed to problem down to my indicator, basically when i try to set the lastBarColor = barColor as below it is not stored and i can not recall the color, i have created the variable as public for ease of access

Color barColor = (Values[3][0] > Values[0][0] ? BarColorUp : BarColorDown);
lastBarColor = barColor; // <------here is the assignment
DrawLine(CurrentBar.ToString(), 0, Values[1][0], 0, Values[2][0], ShadowColor, DashStyle.Solid, ShadowWidth);
DrawLine(CurrentBar.ToString() + "OC", 0, Values[0][0], 0, Values[3][0], barColor, DashStyle.Solid, ShadowWidth * 3);


any ideas would be welcome im a bit stuck

Thanks

Please see this reference sample instead of declaring as public: http://www.ninjatrader-support.com/v...ead.php?t=4991

You most likely need to use the Update() method as described in that sample.

[arilano]

yep thats exactly what I need

thanks for pointing me in the right direction


Much appreciated

h-ok ive set the variables to protected and am using the get set functions, i have included Update(); calls in the functions but still the bullindicator bool is not being set and i hence my strat is not executing anything because the bools are not changing

barColor = (Values[3][0] > Values[0][0] ? BarColorUp : BarColorDown);
DrawLine(CurrentBar.ToString(), 0, Values[1][0], 0, Values[2][0], ShadowColor, DashStyle.Solid, ShadowWidth);
DrawLine(CurrentBar.ToString() + "OC", 0, Values[0][0], 0, Values[3][0], barColor, DashStyle.Solid, ShadowWidth * 3);


if (barColor == Color.Lime)
{
bullIndication.Set(true);
bearIndication.Set(false);
}

elseif( barColor == Color.Red)
{
bullIndication.Set(false);
bearIndication.Set(true);

}...


and for the update part ive got

public BoolSeries BearIndication
{
get { Update(); return bearIndication; } // Allows our public BearIndication BoolSeries to access and expose our interal bearIndication BoolSeries
}


Im still not getting the value i need, all i want is the bar colour of the last candle

apologies if this is outside the scope of support but im at a dead end

Thanks

Could you please post the strategy and the indicator files instead of snippets? It is hard to determine their relationship from snippets. Thanks.

Hi

I've had an idea as im only interested in the formula for working out the new real bodies i should be able to do this in a strategy without using the indicator at all, and I will keep this on a back burner or as an exercise to improve my coding.

will be back if if stuck!

Thanks for the help

Hia Arilano,

have you been able to sort out this?

I am trying to do the same without any result

Cheers

i tried this but it didnt work

if (HeikenAshiCustom().HAOpen[0] < HeikenAshiCustom().HAClose[0])
{
do something
}

In your OnBarUpdate(), you need to look at the previous bar, not the current bar.

if (HeikenAshiCustom().HAOpen[1] < HeikenAshiCustom().HAClose[1])
{
do something
}
