CS,
thank you for the input.
There is a difference here.
B. L. Cotton calculates "the future price that would trigger a moving
average crossover". It is useful in WHAT-IF scenarios for the next
bar. [A similar approach was done in Siligardos article for the RSI
and the RevEngRSI].
Both methods give from today the price needed for tomorrow cross.
Nothing more.
You will know the truth of the argument tomorrow, ie the crossover
day. Since we speak for Close price, you have to wait till the end of
the session to verify the cross.
My approach is different, I just predict [today] that an MAcross will
occur tomorrow.
The obvious benefit is the selection of your buyprice/sellprice over
the whole H to L range of the crossover day.
My technique decreases the crossover lag by 1 bar and the statistics
are very good as you may see from the posted examples.
