What are the holding types?

A holding has a type that is determined by a movement type.

For example, the Position holding type is determined by the StockMovement type.

Each holding type has a code (for example P) that can be returned in various reports by the Holding/HoldingType metric.

Holding Type	Code	Description
`Position`	`P`	A holding in an instrument.
`Cash Balance`	`B`	A settled cash balance. For example, the cash from a SELL trade which settled last week is included in this balance.
`Cash Commitment`	`C`	Future cash payment in/out of the portfolio from trading activity, for example unsettled cash from yesterday's BUY trade. Each separate unsettled trade is represented as a unique line in the response.
`Cash Receivable`	`R`	Future cash flow into the portfolio from non-trading activity such as subscriptions, redemptions, fees, taxes etc. This label of "Receivable" is used to capture the class of holding types which represent both Receivables and Payables.
`Cash Accrual`	`A`	Future cash flow that has been classified as an accrual (e.g. accrued dividend from a corporate action)
`Forward FX`	`F`	Future cash flow from an FX forward implemented as a transaction (not mastered as an instrument). A pair of holdings is shown, one for each leg of the FX Forward. Can be generated either by the `CashForward` or `CashFxForward` movement type.
`Order`	`O`	An open order, shown when holdings are requested with orders.
`Order Cash`	`OC`	Future cash payment in/out of the portfolio from an open order, shown to balance the above.
	`OF`	An open order in a FX Forward instrument, shown when a recipe has the `produceSeparateResultForLinearOtcLegs=true` option set. A pair of holdings is shown, one for each leg. Note a balancing `OC` holding is not shown. If this option is not set, an open FX Forward order is shown as `O`.
`Allocation`	`L`	As per `O`, except an allocated order.
`Allocation Cash`	`OL`	As per `OC`, except an allocated order.
	`LF`	As per `OF`, except an allocated order.
	`W`	A holding associated with a constituent in a reference portfolio, shown only when requesting the `Holding/HoldingType` metric while performing a valuation.
