$NYAD

mobern

I tried to set up the sell signal that Joe Duarte often refers to. $NYAD crosses below the 50 day moving average and the RSI is below 50. I wrote the alert as this:
[symbol = '$NYAD']
and [SMA(50,close) x close]
and [RSI(14) <50.0]

It should have triggered yesterday. Please help me correct this.
Thank you

If you run this alert as a scan, it triggers on the 12th. The cross happened last week.




A great way to "test" alerts is to run them as a scan. The same logic is applied in both workbenches. On the Scan you can change the date to run the "alert" against.

@lmkwin correct me if I'm wrong - to clarify for @mobern - an alert will not trigger if the condition is already true when you activate the alert - only if the alert is not true when you activate it and later becomes true.

You are correct. Alerts only trigger at the time that they happen. You could set a nested condition inside the alert, just like with a scan, to alert on prior activity though.

This returns a result if the condition was met in the last 6 days in the scan. I didn't test it in alerts, but I do have nested alerts that return results.

[symbol = '$NYAD']

[
[[SMA(50,close) x close]

or
[[1 days ago SMA(50,close) x 1 days ago close]
and [1 days ago RSI(14) <50.0]]
or
[[1 days ago SMA(50,close) x 1 days ago close]
and [1 days ago RSI(14) <50.0]]
or
[[2 days ago SMA(50,close) x 2 days ago close]
and [2 days ago RSI(14) <50.0]]
or
[[3 days ago SMA(50,close) x 3 days ago close]
and [3 days ago RSI(14) <50.0]]
or
[[4 days ago SMA(50,close) x 4 days ago close]
and [4 days ago RSI(14) <50.0]]
or
[[5 days ago SMA(50,close) x 5 days ago close]
and [5 days ago RSI(14) <50.0]]
