Buy the dip (and then sell again?)

After a very strong and long selling streak the price has clearly found a local bottom and should bounce back up higher up to around $240.

Trade idea:

Entry: $220
Stop: $218
Target: $239

P.S. I'm showing my own indicator on my chart, which you can get here:
I don't know what the perfect period is yet, but the one I set as default does not seem to be too bad.
