Hi Joy,

I haven't worked with explorations until now, but there is already an explorer "Equis - Stochastic Osc - Expert System" in metastock. Maybe you can copy this Explorer and change it for your needs.
There is also a search function in this forum - where you can find a lot of threads about different stochastic explorers.
Additional the help function in metastocks gives you more information about the parameter-settings for different functions like Stoch(5,3)

best regards
ts

This error often comes if a space-character is between a function name and the "("
Maybe you can post your code here to see what the error in the formula is..?

Hi Joy55

This might work a little better. Refer to the User Manual for the correct syntax of each function. MetaStock was telling you that you'd placed a constant inappropriately. If you compare the corrected lines of code with your own attempt you'll see that there are several differences. MetaStock will keep reporting an error until all syntax problems are corrected.

{ColA: BUY}
Cross(Mov( Stoch(13,8),5,S),20);

{ColB: SELL}
Cross(80,Mov( Stoch(13,8),5,S));

{Filter}
ColA OR ColB
