Update options when a stock has a split.
Options are not corrected for stock splits or reverse splits, typically with a "1" after the stock's ticker. For example, all SOS options are now SOS1. So SOS240119C00000500 should be SOS1240119C00000500.
This is clearly stated by the OCC in notice number 50643
SOS Limited (SOS) has announced a 1-for-50 reverse stock split. As a result of the reverse stock split,
each SOS American Depositary Share will be converted into the right to receive 0.02 (New) SOS Limited
American Depositary Shares. The reverse stock split will become effective before the market open on July
6, 2022.
