Friends, A very basic Amibroker formula question from a newbie.
I am trying to write an exploration that finds stocks whose RSI line moved below 70 today after being above 70 for the previous three days. I am not sure how to handle the 'previous three days' part. One way I can think of is Ref(RSI, -1), Ref(RSI,-2) and then checking these RSI values individually to determine if they were above 70. But I am sure there is a simpler way. Thanks, vps
