GP,

For me buy means ema10 goes above ema200 and vice versa.

eventB=Hold(Cross(EMA(C,10),EMA(C,200)),13);
eventS=Hold(Cross(EMA(C,200),EMA(C,10)),13);

Since, I may miss the exact bar when cross happens, I wanted to check 
for the last 13 bars.

I would like to know when this cross has happend, is it in the 
current bar or in 13 bars ago.

BarBB=BarsSince(eventB); 
BarSS=BarsSince(eventS); 

Ema10 is either above or below Ema200.  

Assume, there is a buy cross in the current bar, Ema10 went above 
Ema200.

Just one bar before the buy cross  naturally, Ema 10 is below 
Ema200.  How long Ema10 was below Ema200 before giving the buy cross

BarsBeforeBuyCross =
BarsBeforeSellCross =

Hope, I have expressed clearly.

Warm Regards.
