How it traded

Intraday run. It opened up 2.7% at 0.4596, then ran from the open to the high of 2.16 in 187 minutes through 12 halts.

The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.
