P,
attached chart shows capitulation volume spike
Px bar that produced capitulation volume had range of H=1372.75 to L of 1371.00 Bar identified with red arrow.
I scalped first bounce, took profit, then waited for a retest of the price range of the capitulation bar, which technically occurred 18 minutes later (marked with blue arrow), but my buy limit was 1372.50 because price usually eats further into the capitulation volume bar.
this is a 1 minute chart.
this info and a billion dollars would make me a millionaire.
