Variables

Type	Identifier	Description
IntegerArray	_analystKeys	Use for holding all of the analyst keys duplicated from the specified analyst key and indexed by symbol index.
Integer	_buyAbove	Use for the minimum average signal value above which to generate a buy order.
Integer	_sellBelow	Use for the maximum average signal value below which to generate a sell order.
Integer	_barsToHold	Use for the number of bars to hold a trade open.
Boolean	_enableShorting	Use for indicating whether to enable the trading system script to short symbols.
Integer	_analystKeyCount	Use for the number of analyst keys.
Number	_stopLoss	Use for the percent distance from the current price in which to place a stop order which would limit the maximum loss.
Number	_takeProfit	Use for the percent distance from the current price in which to place a limit order which would take profit after a specified gain.
Number	_trailingStop	Use for placing a trailing stop order which would limit the maximum trailing loss.
Boolean	_isPercent	Use for indicating whether the stop loss, take profit and trailing stop are measured in percentages or absolute values.
