Dahl Trend Indicator

[jnorton]

In TC 2000 i have a formula of

(avgc50-avgc50.15)

This is Dahl's simple Trend Indicator. It takes the stock's 50 day simple moving average and compares it to 15 days ago. if it is positive then the trend is up; if it's negative then the trend is down.

How would I get these values in esignal?

Hello jnorton,

With EFS2 code in version 7.9, it looks like this;

function main() {
    return sma(50) - sma(50, -15);
} 

With EFS1 code in version 7.8 or earlier, it looks like below, which can also be used in 7.9.

var study = new MAStudy(50, 0, "Close", MAStudy.SIMPLE);

function main() {
    var vMA = study.getValue(MAStudy.MA);
    var vMA15 = study.getValue(MAStudy.MA, -15);
    if (vMA == null || vMA15 == null) return;
    
    return vMA - vMA15;
}
