Change colours of bars

[kylie]

Hi,

My apologies if this is a simple question but I've searched around and can't work out how to change the colours of the bars on a chart. Basically I am looking to have:

up bar : green
down bar : red
outside bar : blue
inside bar : black

I tried using "BarColorSeries[0] = Color.Green" when a bar met my criteria for an up bar (and the equivalent for the others), but nothing changed on the chart.

Any advice you could give me would be much appreciated.

Regards,
Kylie.

kylie, I would first suggest working with BarColor here, and then only use the series should you need to change a color retrospectively... http://www.ninjatrader.com/support/h...7/barcolor.htm

Also ensure your rules for triggering the color change are hitting, if nothing plots it could be a sign that they don't evaluate to 'true' leading to your expected bar color change.

Hi Bernard,

Thank you for the suggestion. You were right. The logic is falling over because I do a compare of High[0] to High[1] which obviously fails on the first bar. I haven't written many Indicators before so I am not sure how to get around this. In Strategies, you have the setting to say how many bars to leave before you start the logic, but I can't find anything equivalent for Indicators.

Can you please provide some advice on how to get it to ignore the first bar on the chart?

Regards,
Kylie.

Hi Bertrand,

Thankyou for the advice - so simple I should have thought of it myself! My colours appear to all be plotting correctly now.

Regards,
Kylie.

Hi there Kylie,

I'm just wondering if you ended up getting this to work? I'm looking to do the exact same thing with NinjaTrader regarding bar colors.

(up bar : green
down bar : red
outside bar : blue
inside bar : black)

I have no experience with the program though or creating scripts. Are you able to provide me with the script or something that I can import into the program to allow me to have the same bar setup?

Thank you in advance!
