This is small because I don't believe it affects the overall data but it's still something I noticed.
The default pip/tick size and step is 0.00005 and it should be 0.0000005. the point value also needs to be 12,500,000 and not 125,000

Update, this also has incorrect values for Silver. The default pip/tick size on silver (SI) in SQX is 0.000001, but the actual tick size is 0.001
