Options,
I ALWAYS take half off on a quick double or more on a run up.
If in doubt about the move I take half off on a 50 % run up.
Stops are not always dependable, and a bad turn can turn your profits into a loss within minutes.
Quick moves always feels so much better to get my original cash back in the till.
Swing trades are ok, but the prems can erase the profits from a slow mover.
Today I sold JASO $12 calls at the open for a buck, and considered $12 puts for the possible ride down but did not enter. Figured the 50% retrace thing would stall it, and it did.(Left .20 on the table, oh well I was not sure)
Weeklies are the best bet for lower prems and quick moves for me.
Sometimes $SPY or Q's for trying to guess a general market swing.
Truth is, they are mostly a guess just like stocks.
