I have overcome this hurdle by keeping the timeframe at the database
level (the real limit), then using algorithms or timeframe functions
to generate signals for longer timeframes. You can even chart in the
longer timeframes, but you can't use study tools. I have made a
suggestion to eliminate the drawbacks #1117. The use of linked
charts is also a possibility (see my AFL Library post "Bad Tick Trim
on 5 sec database" for some ideas on how to do this).
