Syntax

C#
public static double RoundToNearestLowTick(
	double currentPrice,
	double tickSize
)
Visual Basic (Declaration)
Public Shared Function RoundToNearestLowTick ( _
	currentPrice As Double, _
	tickSize As Double _
) As Double
Visual C++
public:
static double RoundToNearestLowTick(
	double currentPrice, 
	double tickSize
)

Parameters

currentPrice
Type: System..::.Double
Current price value.
tickSize
Type: System..::.Double
Tick size. This is the smallest allowable increment of price movement for a contract.

Return Value

The rounded tick value.

Remarks

This is commonly used in futures contracts where the tick size is variable. Similar to RoundToNearestTick, this will round the tick up with a low side bias. With S&P 500 futures where the contract trades in $0.25 increments and the price of the underlying or a calculated value does not fall within the tick increment, use this to push to the nearest lower tick. So if a system were to request an open position and the S&P contract and the requested price was $1000.23, the next lowest tick value would be $1000.00. This is useful in a situation where a system may want to go long with the S&P and the highest price was $1000.23, but according to the system, it should get filled and RoundToNearestTick would return $1000.25 resulting in a non fill.
