I forgot to mention that the maximum time span that needs to be examined is
45 days, the processor is an AMD 1000 and there is 768 MB of RAM that is NOT
DDR. The computer is a PowerSpec from Microcenter bought in early 2002. Ron

  I am running some custom smoothing code on EOD data, and this smoothing
code is used for actual trading purposes, not for backtesting.   

  There are 230 different ema's, and all of these ema's are AFL functions,
as opposed to price or volume. The  average number of bars in each of these
230 AFLfunctions is 23, which gives a total of 6290 bars that have to be
examined for each day that the code is run. 

  What values should I have for IN MEMORY CACHE, and NUMBER OF BARS TO LOAD
in Preferences>data. 

  Remember, this only for finding real life trading setups, not for
backtesting.  TIA for any suggestions.  Ron D

    Ed,

    Go to Tools->Preferences, "DATA" tab and enter 11
    into "In-memory cache" field.
    This will solve your problem.

    Best regards,

I have 500 MB internal memory. When I do a backtest (on the
    complete NYSE or NASDAQ market -I use QP2-) it uses all the memory but
when it is finished it still uses 448 MB memory, it does not
    free it. I noticed this is the same basicly on another computer (which
has 256 + 128 MB memory). But this AMD Athlon is slowed down
    dramatically by the process, it basicly paralizes my computer. Only by
exiting Amibroker I get this memory back. Never noticed this
    being this dramatic before (also because usually I do not do a backtest
on a complete market). Is this a computer problem you think?
    Or do I need to change a setting in Windows?
