Set a Trailing Stop with the previous end of day close as marker.
Share retracement will trigger the trailing stop based on a percentage retracement of the previous end of day's close. Changing daily, automatically.
The daily increase's on end of day close advance the trailing stop incrementally.
The trailing stop does not retreat when the share price retreats, this ensures your profitability or capital is protected automatically.
The only matter of caution is the retracement percentage you set.
If it is too tight you sell unnecessarily.
If it is too loose you lose more capital before the trigger is activated.
I hope this helps
