hi cyw,
if i had to hazard a guess, i'd say bhp has done waves 1, 2, 3 & 4 up since ~$8.25, and wave 5 up is underway now (should at least get above $11.50)...
this view is supported by the daily macd & rsi...
however, i'm not confident on bhp - if i was long (which i'm not) i'd have close trailing stops...
regards,
ultrafart
