[amibroker] Re: TD Pressure Ratio Indicator

["Dave Robinson" <robinson_dave@xxxxxxxxx>]

I think "up" and "down" should be C - O.  Up would then be positive
(+) differences while "down" would be negative (-) differences.

The rest of your AFL makes sense to me.  How would you incorporate the
above into your AFL?  Is IIF required?
