CashSameDay - model a cash account where sale proceeds can be reinvested the same day
CashNextDay - model a cash account where sale proceeds can't be reinvested until the next day
Margin - model a margin account (default)
Notes
This setting affects backtests and order generation in the following ways:
•In the Margin account model, MinFreeCash defaults to unlimited (can become negative) while in either Cash model, MinFreeCash defaults to 0 (can't become negative).
•In the Margin and CashSameDay models, proceeds from sales made today can be used immediately to buy other positions, while in the CashNextDay model there is a one-day delay before those proceeds can be used.
