$CSTL Double Bottom Buy?

NASDAQ:CSTL   Castle Biosciences, Inc
I've had this on my watch list for some time now. It looks ready to break the short term down trend line out of a double bottom pattern. I have an alert set to tell me when it hits the trend line which is just over the $50 mark and it would retake the 50 day MA... I also like the buying volume that has come in the last 2 days. If I get triggered in my price target is the old highs around $55. All TBD . Ideas, not investing / trading advice.
Trade active: $CSTL trade triggered. I have opened a 1/4 position size at $50.85 Stop will be below today's low. It either keeps going up or I'm out.
Comment: Added @ $51.50 bringing up to a 1/2 position.
Comment: Took 1/3 off into highs @ $57.05 for 11.5% profit. Will let remainder ride for additional gains. Stop moved to 5% profit on remainder. Can't lose trade at this point.
