P.O.
Don't get too defensive when I talked about TS.
My mesg did say something good about its easylang
and that it is hard to duplicate the same
in other scripting lang at the same abstract level :)
You are right that you have to define the expressions
first in EL to achieve the speed gain though.
And yes, after disappointment caused by TS and TW,
I will deliver another trading platform - but I am
still a TS owner and will still be a trader as always.
We will see how far our app will go :) One thing I
am sure is that my app will keep improving while
I am using it real time. I do not anticipate
competition from TS at all because I expect they are
dropping out of the standalone app arena :)
Just like the Window on Wallstreet satellite version,
I bought it, thought it will do the job, it was
buggy and after multiple releases no improvements.
Then omega bought it, next thing I know Omega
dropped the satellite version - what should I do?
I am not whining about functionality, but pure
killing of an app because omega bought the
company to kill off its competition ...
