Bullish and Bearish Scanner

[Lds3435]

Hi,

Trying to create a scanner with this condition:

Bullish:

low is above the 21 day EMA for a least 10 days
21 day EMA is above the 50 day SMA for at least 5 days
50 day SMA is in an uptrend
close up for the day

Bearish:

21 day EMA crosses under 50 SMA
Close 10% below recent high and below the 50 day SMA


Thank you much!

Thank you much!

here is an upper study for you to experiment with.
it draws vertical lines for bull and bear signals

for bear, at 10%, i never saw any bear signals. i changed it to 0.5% to be able to see some signals. with a cross below AND a big drop, it is highly unlikely to work at 10%.


to use as a scan , ( or as a lower for testing) , add

plot z1 = bull;
or
plot z2 = bear;

and disable the existing plots with #

# avg_bullbear_scan_00
