Ron --
I believe you are correct. I haven't tried it for explorations. But I
have for back testing. Back testing takes the same amount of time
whether you do it for the last 30 days or the last 3 years. It also
takes much longer for the first time you run it than for following
times, because much of the data is cached from the first time (assuming
your computer hasn't been very busy between the two backtests and you
have lots of RAM).
I believe that Fred Tonetti's IO runs as fast as it does because he
writes a new temporary data base with just the number of bars that IO
will need. I hope someone corrects me if I'm wrong.

exploration looks back at the most recent 100 days of data, then it
will run the fastest if your trading database is only a little larger
than the 100 days of data that you are analyzing.
If you have 1000 days of data, your exploration of only 100 days will
examine all 1000 days worth of data will take longer. Ron D

Go to Tools > Preferences > Miscellaneous and check Display chart
timing(advanced) and see which custom indicator is causing your
problem.
