@AverageJoe Check out tradingview.com - the real thing.
It is the (stripped down) engine used by the CME (if you click the tiny chart icon on say a Gold Futures quote, any instrument), and the locally very popular investing.com, if one looks closely at the bottom "Powered by tradingview.com"
It's R/T, largely free, tho' some features are Premium . Unfortunately it does not (yet) support ASX, and I have raised it with them. I may do it again.
Let me print a chart of USDJPY...I will say in advance (no pun intended) - without looking, it has the A/D line as an available indicator. Assuming that, I'll add it, but already full of my other indicators.
Yep, it's there (as is the A/D ratio)...I've put it at very bottom - TV strongly recommended.
