Money Flow vs OBV

[wbosher]

I'm reading Technical analysis of the Financial Markets by John Murphy and I'm up to the part where he is talking about Volume. He has just mentioned an indicator called "Money Flow" which appears to be similar to OBV but a little more jumpy (I've just compared the two on the NZX website). It looks pretty good to me but I'd like to know what do you experienced TA's think of this indicator? I've seen OBV mentioned often on this forum but I haven't come acress Money Flow yet.

This is a really good book for TA newbies like myself, the only thing I don't like about it is that it isn't specifically for stocks (which is all that I'm interested in at the moment), it spends quite a lot of time talking about futures. A very small gripe, but otherwise a great read.
