• Ratio — Indicates the quantity of each leg in relation to the others. A negative sign (-) before the number indicates a short leg. Values entered in the Ratio field do not affect the spread price.
• Multiplier — Weights the value of the leg price to calculate the spread price when using the "Price Differential" formula:

(1 * Leg1.MergedPrice) - (1 * Leg2.MergedPrice)

Note: The multiplier can be a whole number, decimal number, or fraction. Fractional representation optimizes ticking accuracy.
