Hi jshee,
First create an indicator with your requirements b/c it would be easier to adjust later if necessary:
{NAME: EMA Cross}
x:= Mov(c,50,E);
y:= Mov(c,200,E);
z:= cross(x,y);
IF(40>BarsSince(z),1,0);
In the filter tab of the explorer write down:
Filter: FML("EMA Cross")=1
// Keep in mind that this is for the 50D EMA crossing ABOVE the 200D EMA. IF you want the opposite you should change the "z" variable in the indicator to z:=cross(y,x).

Hi jshee
Make sure the Explorer is set to around 1000 records so that your 200 day EMA is accurate. You might get away with 800 but I wouldn't recommend anything less. If you were to use the Explorer's Minimum Records setting your results would be quite useless. This is becaue an EMA uses ALL available data to generate a result, not just the "periods" number of bars. As a rule of thumb I suggest multiplying the longest EMA "periods" value by a factor of 5 to determine the number of records to load. The same rule should be applied to every function that uses an EMA (or Wilders Smthing) internally; common examples of such functions are ADX, ATR and RSI but there are also many others.
