Decimal Ratios in Autospreader
Decimal Ratios allow users to create more precise spread definitions when creating synthetic spreads in Autospreader. When using ratios in Autospreader, it can become very difficult, if not impossible, to send an Autospreader order that will generate an order quantity in one of the legs that matches your requirements.
Consider a U.S. Treasury futures spread between 5-Year T-Notes (ZF) and 10-Year T-Notes (ZN). The proper ratio ratio between these contracts may fluctuate, but for our example, let’s assume that the proper ratio is 1 ZF contract to 0.625 ZN contracts. In whole numbers that would require a ratio of 8 ZF to 5 ZN. It would be impossible to execute an order for 100 ZF as the Autospreader order could be 12, equal to 96 ZF, or 13, equal to 104 ZF.
