	Hi Bruce... Ninjatrader would be the way... it has tick charts and its free, also forex data is free there... so far had tested quite a lot and has a very friendly charting functions and no connection issues (very important )... I would love to get a chart on Ninjatrader similar to Unicorn`s on amibroker... hope we get there... The edge of using Tick charts on forex is being able to get a very good precise timing... even better than the 1 min we actually have on mt4... I dont know how their coding language differs to mt4... but if we could migrate there, it would be worth the effort eventually... cheers Walter.

It uses C# which is not only for indicator programming, so it has more stuff but is also a little more complex but with less limitations. I haven't coded MT4 stuff but from what I have seen I prefer NT.

Things that are missing in NT: using data from other time frames in an indicator
Also the indicator on indicator thing is not possible to configure on the chart, but is easy to do in the code.

	Walter What data feed are you using to get free forex data into NT? Cheers Blu-Ray

NT has already included Gain forex data... now, there is one parameter where I choose ninjatrader servers and get historical data (up too 2.5 years)... much better data also... really its a very friendly platform..

Take care Blu ¡¡ cheers Walter.

	Now let me ask again inputs : Unicorns _Cyan line _ Red line

Cyan: ADX:3, EMA:3, Stoch:5, MA:2
Cyan: ADX:5, EMA:5, Stoch:10, MA:2

I haven't looked into the rainbow yet, the MA stays constant all the time.
Don't think it will take much effort.

Cheers

Good day Sparrow;

in your code:

double adxMin = MIN( ADX( Low, ADXPeriod ), StochPeriod )[ 0 ];
double adxMax = MAX( ADX( High, ADXPeriod ), StochPeriod )[ 0 ];

are you certain that these lines of code compute

adxmin = LLV(adx, stoch_period) ;
Lowest value of adx in the last stoch_period bars ?
and
adxmax = HHV(adx, stoch_period) ;
Highest value of adx in the last stoch_period bars ?

adx in my implementation is computed on the close. (as is usually done).
Does the Ninja Trader have the HHV and LLV functions?

cheers.
Unicorn.

Unicorn : what are the ma`s increments to form the rainbow from 1rst yellow all the way to the magenta ... ? thanks Walter.

Hi Unicorn,

Thanks for reviewing my code, you're right I got confused with LLV and HHV.
NT hasn't got LLV or HHV, but ADX produces only 1 value per bar so it is not necessary. Otherwise can be done by MIN( Low, Period ), MAX( High, Period ).

Fortunately the glitch does not produce very different results.

Cheers and thanks

Walter;

the values I have used are also depicted in my charts, in the following notation:

In vmar_1
cyan line is: signal vmar_1(ema_periods, adx_periods)
and
red line is: rainbow base vmar_1(ema_periods, adx_periods);

Note that in vmar_1 implementation, stoch_periods = adx_periods.

In vmar_2
cyan line is: signal vmar_2(ema_periods, adx_periods, stoch_periods);
and
red line is: rainbow base vmar_2(ema_periods, adx_periods, stoch_periods);

Usually I have used:

signal vmar_2(ema_periods=3 or 4, adx_periods=4 or 5 or even 8, stoch_periods = 4 or 5 or even 8, 10)
and
rainbow base vmar_2(ema_periods=5 or 6, adx_periods=4 or 5, or even 8 stoch_periods = 4 or 5 or even 8, 10)


Take care.
Unicorn.

Thanks unicorn, mixed up the values because I compared your functions parameter's order to the values on the chart.
Looks much better now.

Ok I see... now from that base line (red line) would the rainbow averages be 2 , 4 , 6 , 8 etc until 100 ? or what numbers exactly... thanks Walter.

Sparrow;

In your code, I cannot locate where you compute the rainbow , i.e.


for (rainbow_ema_periods=2; rainbow_ema_periods <=100; rainbow_ema_periods=rainb ow_ema_periods +2)
{
rainbow_line = EMA( rainbow_base_Vidya , ema_periods) ;
plot(rainbow_line, .....);
}

please verify that this loop is correct in your code ( that may be the minor bug you mention)

best regards.
Unicorn.
