How strange is it that on the very day this exchange took place I was
struggling to convert the EL indicator displaced code into a system. Twelve
years of using TS, never once looked at a displaced MA system and here are
two of us on the same day...
Of course, I failed. No way I could code that displaced MA to give me
today's value. But I'd like to take one more swing at why not.

foolsgold suggested:
System
input: Price(close), Length(5);
Value1=(WAverage(Price,Length)[1]);
if value1 > value1[1] then buy next bar at market;

I'm working with a MA displaced into the future (-3) periods. Of course, I
can't initiate a trade three bars into the future, but I can see the value
of that MA on the current bar. I can bring up a data window and see both
the close of the current bar and the value of the MA in the current bar.
So why is it not possible to code the entry to say, "If current bar close is
above the displaced MA(-3) [4] " or something to indicate that the trade's
to take place today using today's figure? If TS can generate the number for
the current bar in current time, why can't the signal see it?
Foolsgold system looks at the value of a MA in the previous bar, but it's
not a displaced MA that he's trying to drag back from the future.
Gary, or anyone else, can you point out the fault in logic? Or suggest a
way to get the MA code working?
Many thanks,
