Just saying; no offence:
This has obviously nothing to do with kvak (who added a button) but
as far as terminology goes, this indie is useless:
Dow Theory:
in an uptrend you have: higher highs (HH) and higher lows (HL)
in a downtrend you have: lower lows (LL) and lower highs (LH)
Whoever coded this indicator obviously didn't have a clue about that.
