For the range bar case in particular, you can give 100% accurate minimum and maximum bounds on an event, as described here: RWT-006 ... which to me makes it the most interesting case. There are times when your price indicators basically have no choice but to go somewhere within n-bars, because there is a strict bound on where price itself can go within n-bars. I think this is an under-utilized phenomenon in TA .... since if you are trying to identify the explosions it won't do at all to assume price never moves [P.S. I don't mind being called Gary as long as you keep linking to my site ]

oops ... did I mention the lack of caffein??

Thanks for your work, RICHARD !

Mike: about those different moving average types ... lol

I think I'll go play with that 'under-utilized phenomenon' ... RICHARD's 'predictive' algo is about to be downloaded ... let's see if aggressive or conservative can also be predicted

Thanks to all

I can't wrap my head around this. So lets say we want the close[0] where a 200 SMA will Cross the 50 SMA one bar (Period) ahead of time. Couldn't we just set them equal to each other using:
X = Close Needed
A = SUM of prior 199 Closes
B = SUM of prior 49 Closes

(A + X) / 200 = (B + X) / 50

Solve for X or (New Close)

X = ( A - 4B ) / 3

***Or is this really bad algebra? What am I doing wrong, or is this the wrong approach?

CrossClose[0] = ( SUM(199)[0] - 4*SUM(49)[0] ) / 3
