The time it takes to build the trendlines is dependent on the following:
 Number of family members
 Size range for trendlines to be built. If you use 1 to 20 vs. 1 to 10 it will take
twice as long because twice as many trendlines need to be built.
 Selecting the Optimized logarithmic vs. linear option will double the set up time
because both versions of trendlines will need to be calculated. If after
experimenting you always find that the Log version is being chosen then using
only the Log version in the optimizer will reduce the run time by half.
 Your computer speed
It doesn’t matter if you choose only the trendline Stop rather than both the trendline Stop
and the trendline Buy Filter. The same trendlines calculated are used for both options.
Note: The trendlines are not saved when you save a FastBreak Restart file. If you load
a FastBreak Pro Restart file the trendlines will all recalculated. Therefore, if you
think there is a reasonable possibility you want to use the optimum strategies found
during an optimization run then it is best to save the best generation strategies at the
end of an optimization run rather than loading the Restart file at a later date.
Data Required to Determine a Trendline
It can take a considerable amount of historical data to determine the first trendline. This
is because it requires two meaningful dips (in the case of an upward trendline) to create
the first trendline section. If the stock or fund is in a significant upward movement at the
beginning of its historical data, then no trendline can be drawn. Until a trendline can be
drawn, FastBreak will assume that the stock or fund is BELOW its trendline. Therefore,
this stock or fund can’t be purchased if either the trendline Stop or Buy Filter is used by
the strategy.
You need to be aware of this issue because you may see situations where a stock or fund
is highly ranked and clearly in an uptrend but a strategy will not purchase the equity.
Repeat, until a stock or fund has two meaningful dips in the equity curve a trendline
cannot be constructed, and therefore FastBreak will assume the issue is below the
trendline and unavailable for purchase.
Will not work with Optimize Family Option
Because the trendline option builds a series of trendlines for each member of a trading
family this makes it impractical to use with the Optimize Family option.
When the
Optimize Family option is checked, a new family is built every time a new strategy is
evaluated.
This would require building trendlines over and over again and the
optimization run time would be prohibitive.
