In a strategy the maximum number of trend pens is 8. Therefore, if you have already
put in your strategy two modules of type 4TP, ( Four traces trend panel) you have
reached the maximum number of traces. Therefore, you cannot add any further
Trend Panel of type 2TP and TRP, even if you have exceed the maximum limit for
these types of modules. and even if you still can add 10 more display panel.
Furthermore, beyond the trend limits and the maximum number of 12 modules, you
have another important limit on the display panels; you cannot have more that 9
display modules of the same type in the strategy.
