Here are my normal target rules.
For non pennies swing trades 10% $2.00 to $5.00, 5% $5.00 to $10.00, and 2.5 % $10.00 to $20.00. Don't play higher. Don't go long! All loss targets 1/2 the proift target.
For penny swings, under $2.00, 25%, loss 12.5%;
Day trades, Target moves 10% above the last held PPs in 3 steps. 1/2 first buy, 1/4th 10% lower, 1/4th 5% above 2nd. loss target 20% from first buy.
Long a double! loss 15% below first buy! Add when I have EXTRA cash, 10% of original buy each time, only twice, each 5% below the last drop or 5% retrace after pop. Will result in about 20% loss or 20% larger gain.
Pick your own, but stick to them.
