Simple SMA indicator (Didi Index)

[AChammas]

Hello guys,

I am new on NinjaTrader and I don't know how to make an indicator but I need to programming a new one. It is very simple.

The indicator is composed by 3 simple moving averages. The SMA are 3, 8 and 20 but all of them are divided by the SMA 8. So the SMA8 will be plotted as horizontal line and the others two SMA will be the SMA(3)/SMA(8) and SMA(20)/SMA(8), all 3 SMAs are plotted on the same panel. Could someone help me with this indicator.

The SMA(3)/SMA(8) is blue, the SMA(20)/SMA(8) is red and the SMA(8)/SMA(8) will be an horizontal white line.

I have this indicator on my Tradingview website and the code that works perfectly is:

study("Didi Index")
sma1=sma(close, 3)/sma(close,8)
sma2=sma(close, 8)/sma(close,8)
sma3=sma(close, 20)/sma(close,8)
plot(sma1, style=line)
plot(sma2, style=line)
plot(sma3, style=line)

The problem is that I don't have an idea of how can I do it on NinjaTrader 8.

This is how it is appear:

Hello AChammas,

Below is a public link to a forum post with helpful information about getting started with NinjaScript.
https://ninjatrader.com/support/foru...040#post786040

I would recommend starting with the Strategy Builder and copying the logic and variables only over to a new generated indicator as demonstrated in the NinjaScript Editor 401 course.

Yes, I would like to know how much will cost to have someone build this indicator for me. I know that is a work for 10 min because it is very simple to someone that knows the language. So please give some information on how can I quote this indicator job?

Thank you,

Hey, buddy, what's up?

Did you get the Didi Index, either free or paid? I'm looking for it for NT8 and I'm not getting it.

If you can, give me a return.

Thanks, man.

We look forward to assisting.

Hey @AChammas

I do not think any programmer would code anything for less than $100 or at least 2-hr time rate. So, I am asking you to donate generously for this free indicator to the charity Children's Hospital Los Angeles here: https://www.chla.org/ or any charity of your choice serving children with cancer.

Amigo, tudo bem?

I usually do not code or post forex newbee scripts, unless they have some solid purpose or proven trading methodology behind them. But, I was asked for it by bhrunogomes and coding this indicator beats fighting Covid-19 brain drain. So, here is Just another MA oscillator indicator not worth my time.

Frankly, people would be much better off by simply using the MACD instead, the mother of all MA oscillators.

Cheers!

Its good to see fellow traders helping the trading community when they can, and also donating to the less fortunate. Nice one Aligator! Which we had more guys like you mate

First of all I want to thank you for taking the time to develop the indicator and I affirm that it was done with mastery. Congratulations and thank you very much.

Having said that, if you will allow me, I would like to explain a little about the purpose of the indicator so that perhaps you can change a little the bad concept you have of it.

As you could see, it is nothing more than a crossing of averages, where we have an entry when the lower average crosses the fixed horizontal line and the confirmation of this entry when the higher average crosses or remains in the opposite direction of the lower average.

Logically it is not absolute, I use it together with DMI (8-8) and TRIX (9 with average of 4). When the 3 indicators are speaking the same language, the GAIN is mostly accurate.

The request to transform these averages into an indicator is simply to avoid polluting the graph, and to give a cleaner and more accurate view of the averages 3 and 20 crossing the 8.

I invite you to make a backtest and I am at your disposal to clear up any doubts.

Once again, thank you very much.

God bless you.

Thanks for kind words. No worry, English is my 4th language without a translator.

I don't have a "bad concept" about DiDiIndex, it is just another MA cross over. All price-based MA oscillators behave similar and depending on parameters and time frames produce the similar results. I have seen or created many of them for just about any trading platform out there in my 45 years of trading. They all look good in SIM accounts.

Here is a comparison of a few MA crossover indicators (DiDi, mahKDJ, LBR310, my own special sauce, MACD, etc.). You can see that any of them would give similar (or better) results compared to DIDI when parameters are optimized.

Also, note that you would get the exact same crossover results if you simply plot 3 SMA and 20 SMA on the chart instead of DIDIIndex. See the second screenshot.

I actually think my simple mahKDJ indicator (in NT Downloads) gives better indication of short term trend reversals on crosses, if you want to give it a try. Regardless, I have narrowed down oscillators into my own special sauce indicator, the only thing I use.

Cheers!

p.s.
DMI(8) or DMI(8,8)? There is only one period for DMI. Also, TRIX is only a visual indicator and can not be used in real trading. Could you please post a screenshot of your chart showing indicators, time frames, and instrument used

Dear Alligator.

Thank you for making your point.

I'll provide the prints and try to better explain the items you questioned me.

I looked for your indicator to compare with the Didi and couldn't find it in the "downloads" section. Am I doing the wrong research? Can you help me?

Hi,

You can see the comparison in the above screen shots. Just compare DiDi crossover to a simple crossover of 3 SMA and 20 SMA plots on the chart and there is no difference.
