MACD from another timeframe

[JDW]

I am trying to create an indicator that will plot a 30 minute MACD under a 5 minute chart. Is the code below correct? I am only able to plot MACD, and not the signal.

function main(){
var ema12_30 = ema(12, inv(30));
var ema26_30 = ema(26, inv(30));
var macd_30 = ema12_30 - ema26_30;
var sig_30 = ema(9, macd_30(inv(30)));

return new Array(macd_30, sig_30);
}


thanks,
Jeremy

See this thread for a reply to a similar question [the difference being that you are subtracting one series from another instead of dividing them].
You may also want to look at the dsFunctions library which I mention in that thread as it contains a function called dsDiffSeries which subtracts one series from another and returns a series.
FWIW in the EFS2 Custom folder in Formulas you already have a MACD study (ie customMACD.efs) that is enabled for use with multiple intervals and/or external symbols
