corkyalan I do not scan for daily ema at all. My scan is to only ensure that the stock is in an up trend week over week for at least 4 weeks.
Knowing it is up trending for four weeks eliminates the high gap ups and gap downs . Also by being in a weekly trend 90% of the time or better your indicators are going to be positioned correctly anyway.
This is a more refined version of my original and it does alright for me .
(Bar[Close,D] > .25 AND Bar[Close,D] < 5)
{I use this vs Last so that after hours scans are more accurate}
AND
(Bar[Close,D] >= Bar[Close,W,1] AND Bar[Close,W,1] >= Bar[Close,W,2] AND Bar[Close,W,2] >= Bar[Close,W,3] AND Bar[Close,W,3] >= Bar[Close,W,4])
{I use bar close on the day as the first operator, because bar close on the week can give you funky results}
AND
(Bar[Low,D] >= Bar[Low,W,1] AND Bar[Low,W,1] >= Bar[Low,W,2] AND Bar[Low,W,2] >= Bar[Low,W,3] AND Bar[Low,W,3] >= Bar[Low,W,4])
{... because the standard def of an uptrend is higher highs and higher lows, you can't leave out this part}
What we see depends mainly on what we look for.
