You enter an intraday trade long, and the trade immediately goes against you.
What do you do? Here are several possibilities:

1)You exit the trade at your preset stop and wait for a new entry
2)When the price action hits a support point, scale in
3)When the price action drops below a support point, reverse the trade and increase size.
4)exit on the close of the day and take a loss whatever that is.
5)exit when my risk tolerance is hit.

There may be other options.
Let's here from you and tell us what you would do.
