Hi Alan

There is no "quick" explanation. I'll probably go with MACD since it's the easiest. All weekly
formulas (for daily charts) are expansions of simpler formulas for a standard data arry (data and
chart of the same periodicy). ADX is quite a complicated formula to start with so the weekly version
is a nightmare to follow.
I'll now include the formulas I started with for ADX and RSI. MACD you can probably work out for
yourself. The explanation will come later.
