Hello this is a great indicator!One question though ...I am new on this and i have tried out to create an alert when colours turn from red to green and the opposite.
Can it be done?

Funny You asked...I just posted a video on ho wto do this...Go to the thread below and check out the video...If you have trouble following the instructions for this indicator make a request on the link below...and I will help you out...

New Video On How To Create Alerts w/ Any Custom Indicator!!!

For example:

- (Amazon, weekly chart)

That's a screen shot of Amazon weekly. The top blue arrow points to the 4-week EMA that your indicator bases the bar color on. It's a 4 week EMA (up & down). The lower blue arrow points to a standard 4-week EMA plotted on price (blue line).

As of the close of this week (last week in Oct. 2014), price has closed above the standard 4-week EMA, but not above the 4-week EMA that is plotted by your indicator. Which is why I was wondering if there was some kind of smoothing or if it was based on the slope of the EMA or if the calculations were based on something other than the close of price because it isn't matching up to a generic, out-of-the-box EMA.

Any thoughts would be great. Thanks.

Cheers. :-)
All you have to do is go to the Inputs Tab. It defaults to a 34 EMA for the up trend and down trend. you can modify the UpTrend eMA and the DownTrend EMA values in the inputs tab. If you select the last checkbox it plots the ema on the screen. You can clearly see if the Price (HLC/3) is above the EMA the bars color green. Or red if price is below the EMA. it uses a EMA Avg if you change the values so they are different on the UpTrend and Down Trend. So if you keep the values the same for both...then that is what they use.

If you keep the defaults at 34...and check the last checkbox to show EMA.... and you plot a regular 34EMA as another indicator....Then the plots are almost identical. The difference is the EMA's I use are based on the True Heikin-Ashi Close. Hence the title....Modified Heikin-Ashi. Whereas the EMA from the the indicators you plot is based off the Close...Not the Heikin-Ashi Formula.

Excellent. That makes sense. Appreciate the reply and info. Thanks.

This is the script you were probably thinking of. still uses the HLC/3 to change the Bar color...this filters out false breaks above below the EMA.

That will match any EMA you plot on the chart perfectly

Awesome. Yep, this is exactly what I was thinking of. Much appreciated. :-)
Hmmm... this indicator definitely does not highlight bars based on being above or below a regular EMA (a standard EMA pulled from the "Built In" section). At least, not on standard bar/candle charts.

If i put a regular EMA on a standard bar/candle chart and then plot this indicator as well, there are times when price closes above or below the regular EMA and this indicator does not change color to reflect the fact that price has closed above/below the regular EMA. On weekly charts, it's quite a bit off.

Is there a smoothing applied to this or is it based on the slope of the EMA and not the price closing above/below the EMA? In the code, it appears to me, that the color change might be based off an EMA closing related to Heiken-Ashi bars. Is that the case?

I appreciate your work and time. Any thoughts on this would be great. Thanks.
