Confirmation by a slower Timeframe

[laocoon]

Baruch,

I played a bit with the "Closes" concept and it works well when I use it like you suggested, ie:
Closes[1][0]

With the MACD however, the expression MACD(12, 26, 9)[1][0] <0 produces the following error message:
Cannot apply indexing with [] to an expression of type 'method group'

I understand the error message, but I don't know why it appears in this case because I use the same MACD expression in my single-timeframe code a lot without any problems.

Any pointer as to what I'm missing would be greatly appreciated.

Thanks

Hi laocoon,

Here's what you can use for MACD calculated on secondary series:

double secondarySeriesMacd = MACD(Closes[1], 12, 26, 9)[0];

Brilliant, thanks a lot RyanM.

Happy New Year!

if (BarsInProgress == 1) //Code for slower timeframe

{
if (Open[1] <Close [1])
{
SlowTimeframeLong = true;
}


if (Open[1] >Close [1])
{

SlowTimeframeShort = true;
}

}

Look again at this code section, and you will see that after the first green and red bars, both your bools are identically true, as you have never reset them. Therefore, they are now essentially ignored and do not gate your faster time frame signals anymore.

Thanks for pointing that out Koganam, I was struggling with the "BarsInProgress" approach anyway (probably also because of the mistake you highlighted) and find the "Closes[1][0]" way of incorporating a second timeframe much easier.

RyanM,

Just a quick question: I'm using the "Closes" command and it works very well, but I'm still having
some trouble with its syntax from time to time. For example, when apyling it to the Slope function, I'm getting an error message.

Here's the original code snippet: Slope (SMA(20), 14, 0)
When I add the "Closes" bit, it doesn't work anymore so I guess I'm getting something mixed up here:

Slope(Closes[1]SMA(20), 14, 0)[0]

Thanks for giving me a hint.

Hello,

When you want to output an indicator value of a secondary series you would need to do the following.

SMA(BarsArray[1], 14)[0];


This is detailed here in the section using bars objects as input to indicator methods.

Hello Brett

Thanks for your reply. I found the "Closes" method much easier to implement than the "BarsArray" method and use it already successfully with a few other indicators. RyanM was kind enough to show me how it works when he posted this example for the MACD:

"Here's what you can use for MACD calculated on secondary series:
double secondarySeriesMacd = MACD(Closes[1], 12, 26, 9)[0]; "

I want to achieve exactly the same thing with the Slope indicator, but as I said I somehow got my syntax mixed up.

Thanks

[NinjaTrader_Brett]

Yes you can use this way.

Slope(SMA(Closes[1], 20), 14, 0)[0]

Thanks Brett. I did as you suggested, but I'm getting CS 1501 & CS 0021 Error Messages for the following code:

if (Slope(SMA(Closes[1], 20), 14, 0)[0] >-5)
{
LongEntry = true;
}

Thanks

[NinjaTrader_Brett]

Try this:

if (Slope(SMA(Closes[1], 20), 14, 0) >-5)

Compiled on my side when I tested. Slope is not a data series method.

Brilliant, thanks a lot for your help Brett.

Hello Brett

Sorry to bother you again with a small syntax issue, but I'm having trouble getting the following snippet to compile: (the condition is that the latest candle of the secondary series closes above the 100 SMA of the secondary series.

(Closes[1][0]> SMA(100)[1][0])

Thanks for helping me out.

SMA(Closes[1], 100)[0]

Thanks a lot Brett, have a great day.
