Hi Alwin
Calculating the price required for one EMA to cross over (or under) another EMA is possible and somewhere I have a formula for calculating the price required for that to happen.
As I recall, the TASC articles related to a simple moving average and price. The maths for SMAs is quite basic.
Calculating a price needed for that price to cross an EMA is the easiest calculation of all and for one simple reason - an EMA ALWAYS moves TOWARDS the price it is averaging. This trait is inherent in the way an EMA is constructed.
What this means is that for an EMA to touch the price, today's price must move to the value of yesterday's EMA. Therefore the effective price/EMA crossover value is always yesterday's (the previous bars) EMA value.
Regards
Roy

Alwin,
The Feb and Mar 07 issues of TASC carried a 2 part article on
Anticipating MA Crossovers. I haven't studied the articles extensively
but I think they were addressing the issue you have in mind. They are
probably archived at www.traders.com although you may have to be a
subscriber to view them without cost.
I hope that helps,
Jon
