Ratchets and Splits
Ratchets (also misspelled rachets) are fixed prices around which the Emini S&P500 (ES) is said to pivot based on the last 2 whole numbers of the price. The last 2 whole numbers of the ES at their extremes are 00 and 100. Using these as starting points we split them 4 times to get all of our ratchet levels at 6.25 points apart.
00.00
06.25
12.50
18.75
25.00
31.25
37.50
43.75
50.00
56.25
62.50
68.75
75.00
81.25
87.50
93.75
100.00
```If the ES is trading at 1180 then the next ratchet level above it will be 1181.25 and the first one below it will be 1175.00.
