strategy
METADATA: initial_cash
initial_cash: number
Initial cash.
Default is 100000.
METADATA: pyramiding
pyramiding: number
The maximum number of entries allowed in the same direction. If the value is 0, only one entry order in the same direction can be opened, and additional entry orders are rejected.
Default is 0.
METADATA: allow_entry_in
allow_entry_in: direction
Used to specify in which market direction the strategy.entry function is allowed to open positions. Possible values: direction.long, direction.short, nil.
Default is nil.
METADATA: commission
commission: string
Commission for each transaction.
The format is type=value, where type is one of percent, fixed, cash-per-contract.
You can use multiple commissions by separating them with a comma (e.g., percent=0.1,fixed=10).
Default is ``.
METADATA: initial_margin_long
Margin rate for initial short positions.
Default is 1.0.
METADATA: initial_margin_short
Margin rate for initial short positions.
Default is 1.0.
METADATA: maintenance_margin_long
Margin rate for maintenance long positions.
Default is 1.0.
METADATA: maintenance_margin_short
Margin rate for maintenance short positions.
Default is 1.0.
METADATA: slippage
slippage: number
Slippage for each transaction.
Default is 0.
METADATA: risk_free_rate
risk_free_rate: number
Risk-free rate of return is the annual percentage change in the value of an investment with minimal or zero risk. It is used to calculate the Sharpe and Sortino ratios.
Default is 0.02.
entry
entry(id: string, side: direction, qty: number = nil, qty_percent: number = nil, price: number = nil, remark: string = nil)
Creates a new order to open or add to a position.
If the call does not contain price argument, it creates a market order, otherwise, it creates a limit order.
Orders from this command, unlike those from strategy.order, are affected by the pyramiding parameter. Pyramiding specifies the number of concurrent open entries allowed per position. For example, with pyramiding = 3, the strategy can have up to three open trades, and the command cannot create orders to open additional trades until at least one existing trade closes.
When a strategy executes an order from this command in the opposite direction of the current market position, it reverses that position. For example, if there is an open long position of five shares, an order from this command with a quantity of 5 and a direction of direction.short triggers the sale of 10 shares to close the long position and open a new five-share short position. Users can change this behavior by specifying an allowed direction with the METADATA: allow_entry_in.
order
order(id: string, side: direction, qty: number = nil, qty_percent: number = nil, price: number = nil, remark: string = nil)
Creates a new order to open, add to, or exit from a position.
If the call does not contain price argument, it creates a market order, otherwise, it creates a limit order.
Orders from this command, unlike those from strategy.entry, are not affected by the pyramiding parameter. Strategies can open any number of trades in the same direction with calls to this function.
This command does not automatically reverse open positions because it does not exclusively create entry orders like strategy.entry does. For example, if there is an open long position of five shares, an order from this command with a quantity of 5 and a direction of direction.short triggers the sale of five shares, which closes the position.
close
close(id: string, qty: number = nil, qty_percent: number = nil, remark: string = nil)
Creates an order to exit from the part of a position opened by entry orders with a specific identifier. If multiple entries in the position share the same ID, the orders from this command apply to all those entries, starting from the first open trade, when its calls use that ID as the id argument.
This command always generates market orders.
cancel
cancel(id: string)
Cancels a pending or unfilled order with a specific identifier. If multiple unfilled orders share the same ID, calling this command with that ID as the id argument cancels all of them. If a script calls this command with an id representing the ID of a filled order, it has no effect.
cancel_all
cancel_all()
Cancels all pending or unfilled orders, regardless of their identifiers.
This command is most useful when working with price-based orders (e.g., limit orders).
