Hi Mike --
Here is a short AFL code from one of the libraries. You can use whatever lookback periods you want to.
-----------------------
// The Title of the graph will show the price required to generate a crossover of the EMAs.
// for instance, if you want to Buy a stock if the 5 Day EMA crosses above the 10 Day EMA,
// you will know what price is needed to make that happen on the next
// Day by the figure that is displayed in the Title.
// Take the Formula AND the AFL AND work it into your own favorite graphs.
Plot(Close, "Price", colorBlack, styleBar);
Plot(EMA(Close,5),"5-EMA",colorWhite,styleLine);
Plot(EMA(Close,10),"10-EMA",colorRed,styleLine);
//Formula for EMA Crossover Price
XR=(EMA(Close,5) * (2 / 6 - 1) - EMA(Close,10) * (2 / 11 - 1)) / (2 / 6 - 2 / 11);
Title = WriteVal (XR, format=1.2 ) + " Price Required for EMA Crossover";
-------------------
I am the author of "Quantitative Trading Systems." Chapter 13 of my book shows several methods of anticipating crossovers, and other signals, for cases both where you know the formula and where either you do not know the formula or it is too complex to solve.
Thanks,
Howard

Do a search on the Web to find the EMA formula that shows how to
calculate the next day's EMA value. Once you have that, you'd either
have to iteratively try different values to work it out, or possibly
apply a bit of simultaneous equation maths to solve for the next day's
price.
Regards,
GP
