Re: [amibroker] computer Memory usage

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,

  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?
