The tick conversion formula
Ticks = point movement ÷ minimum tick size. Dollar movement equals ticks × dollar value per tick × contracts. This tool reports the magnitude of a move, whether it would favor or hurt a position.
NQ versus MNQ
Both Nasdaq-100 contracts move in 0.25-point ticks. NQ is $5 per tick and MNQ is $0.50 per tick, so the same point move has one-tenth the dollar impact in one MNQ contract versus one NQ contract. The MNQ guide works through the contract math.
Do not confuse tick value with margin
Tick value measures how P/L changes as price moves. Margin is collateral required to hold a position and can change with exchange and broker rules. A smaller tick value does not remove leverage or gap risk.
Check a custom contract
Custom mode accepts the contract's minimum price increment and dollar value of that increment. Confirm both from the current exchange and broker specification before using the result to plan quantity.
