I have opened a chart with Momentum bars, added the Universal Keltner with ADXVMA settings. I have then let it run for a few days via the Market Analyzer. There was no memory leak, but NinjaTrader used about 150 k for the entire period.

minor change to Keltner Universal
I changed a couple of lines of code because I thought there might have been some kind of recursion. I was also having a memory leak when displaying paintbars. It's gone now but there were some other things that I also changed, so cannot be sure that this had actually been a problem. Thanks Harry, nice indicator.

I had introduced the variable trendColor, which should be used in that line, aBarColor is therefore not required. It was just a slip of the pen, the correct code would be
However, the bug would not have caused a memory leak. The only consequence of the bug was that every incoming tick would reduce the opacity of upclose paint bars, when the indicator was set to COBC = false. Nevertheless it was a bug, which should be removed.
BollingerUniversal and DonchianChannel suffered from the same problem (due to my habit to copy-and-paste), the SuperTrendU11, SuperTrendM11, Heikin-Ashi Paintbars, GannHiLoActivatorU1 and MACDUniversal had it already correct.

Thanks to everyone (especially Fat Tails) for their input on this Great Ninja Indicator. I've been using this indicator for a couple of weeks with some decent success, however, I would love to improve upon my results.
In conjunction with this indicator, i've been using RJay's RenkoHybrid Bars on a 12 tick setting (Thanks RJay, great Bars!!).
since RJay's Bars show the real time "highs and lows" and tails on the renko bars, i've adjusted my Reward to Risk ratio from 1:1 to 1:1.5 ( was using a +12 / -12 target/stop, but was getting stopped out quite a bit, then i started using a +12 / -18 Target/stop and have been having a much higher rate of Winning Trades. I know it's not ideal to have less than 1:1, but with "scalping", i've been having more success starting out at 1:1.5, and trailing my stop up as the price moves in my direction).
So, with RJay's RenkoHybrid 12 and the ADXVMA set to 9, and just going long when there are blue bars and exiting at a target of +12, and or exiting at -18 if i get stopped out, and going short on red bars and exiting at a target of +12, or exiting at a -18 stop:
In my experience the problem with this indicator like most others is chop. You can do ok in a trending market but because markets don't trend 70-80% of the time it is difficult to be consistently profitable over the long term.
The trick with backtesting this is have a look at a chart and identify when the instrument is in a trend and when it is balanced.
Test it in both environments. You will see clearly the issues. The secret sauce is have a clear determination when the instrument you are trading is trending and when it isn't and becoming increasingly accurate in this determination. As you become better at this you will know the right time to deploy this indicator and your long term odds should improve.
