[amibroker] Re: Not sure how to create a trigger

["Mike" <sfclimbers@xxxxxxxxx>]

Also,

you may want to rethink your logic to be more restrictive. Just 
looking to see if the RSI was less than 30 *ever* is not going to be 
very usefull. You might want to adjust your strategy for trigger1 to 
be RSI < 30 within some predefined time period (e.g. within last 20 
bars) giving the following:

Buy = BarsSince(RSI(14) < 30) < 20
AND Cross(MA(Close, 5), MA(Close, 10));

If you specifically wanted to measure from the point that the RSI 
*first crossed* below 30 (as opposed to the most recent day at which 
it was *still* below 30), you would use Cross in the first expression 
too:

Buy = BarsSince(Cross(30, RSI(14))) < 20
AND Cross(MA(Close, 5), MA(Close, 10));
