Luc trades naked (the chart, not him). As you can see from his videos, there is no indicators besides volume bars at the bottom.

As for when to sell, anywhere in profit is a good spot to sell. The safest method is layering your sells out until base. Why? because if the chart has always respect bases, the price will likely also return to base this time as well. You can leave a little profit to sell later just in case the bounce goes higher than base.
