Percent exposure limit for positions in the same symbol for a strategy or group of strategies
Input
Any formula specifying a percentage
Notes
MaxSymExp is one of the Capacity Constraints formulas used in the setup selection process.
A setup is only selected if its position size plus those of other setups and open positions in that symbol would not exceed the percent of S.Alloc expressed as MaxSymExp.
If a setup cannot be selected due to this constraint and the strategy specifies Reduce: True, then the position's Quantity will be reduced to allow the position to be ordered for entry at smaller size if possible.
Setups skipped for this reason display "max sym exp" in the Reason column of the Trade List, provided that the KeepTrades setting included Skipped.
If MaxSymExp is not specified then there is no limit placed on same-symbol exposure level, though there might still be same-symbol constraints if the strategy specifies MaxSymInv or MaxSameSym.
Note that opening gaps beyond a specified order price may cause actual same-symbol exposure to exceed the specified cap in some situations -- think of this constraint as "maximum intended exposure to the same symbol".
