Here is a 'very inexpensive' alternative to Juriks Moving Average contributed in Easy Language by John D. McCormick (TS handle = JDM, see jmactrader.com).

Moving Averages are used to remove noise. By “noise” is meant the apparently random motion up and down of the prices around their average price. This shows up on a moving average as a jagged appearance on an otherwise smooth line. The jaggedness can trigger false buy and sell signals or simply make the indicator hard to read, so we try to smooth out the average, i.e. remove the noise.

Lagging or lateness is the bane of moving averages. You make them longer (average in more bars) and the moving average is smoother, but now it lags way behind the actual price movement.

The ideal moving average should filter out noise and respond quickly – and – it would be a plus if it was fast calculating. That’s kind of like having your cake and eating it too.

Nevertheless, here’s one, I call it Quick MA, that seems to work as well as any I’ve seen.

zdo or any other who has QuickMA with tradestation, can you post a chart of the recent ES or YM with QuickMA(9) and possibly HMA(9) on it?
I translated the code to ninjascript but I don't have tradestation to vertify if my code is right or not. I don't think my code is right.

It would be great if you post a recent chart so that I can compare my QuickMA in Ninjatrader with yours. Please tell me if below value match.

ES0309 on Jan23,5min chart,
11:00amCT: Price close: 815.50, QMA(9) 819.87
11:05amCT: Price close: 817.25, QMA(9) 819.15
11:10amCT: Price close: 816.50, QMA(9) 818.36

Here is my chart:



The blue line is my QuickMA and red line is HMA. As you can see, my QuickMA is nowhere as fast as HMA, so I think I may be coding it wrong.. and I need to make sure...

Rurimoon,
I don't have tradestation anymore, but I've converted the QuickMA code from EL and got the exact numbers as you did for the 5min ES. Here's a scrrenshot with my conversion of the QuickMA along with HMA and a conversion I did from what is "supposed to be" JMA converted from Metatrader.

Magenta is HMA
Blue is the converted QuickMA
Black is the converted JMA

Thanks to verifying for me. I have always though that QuickMA should be at least on pair with HMA so I don't believe in my coding skill when I see that it lag behind so much. I am in the process of converting JMA from metatrader to ninjascript also. The problem is I have find at least 5 different version of JMA in Metatrader and I have no idea which one produce more accurate result with the real JMA. Can you tell me which version of JMA from metatrader that you are using? (Of course it would be best if you can share your code

P.S. I have a version of JMA in metatrader that is so cheesy, it has at least 50 variable defined. Basically it change its formula base on which period it used... the code has so many if then else statement that I wonder how long it takes the coder to fine tune all those numbers.

Find attached screenshot with
Red = Hull
White = Quick
Blue = Jma

All set to 4 periods

Hull definitely turns faster
Jma definitely goes flat faster and more smoothly than the other two (and that is about the only utility for mov avgs I have)
Quick came along for free so I shared it for ppl who don’t like to buy closed source products etc.

ie best one depends on your own distinctive needs.

PS rurimoon re "Basically it change its formula base on which period it used"
That particular one is not it...

Thanks for posting that chart. Would you mind posting another one with the MAs overlaid over the candles, too? I want to see how price bars interact with the MAs.

Thanks!

btw did something happen to this thread? I got like 50 emails that there were new replies but there was really only one new reply.
