Why substract 1234 when processing the data

[EternalConfession]

I was very confused why substracting 1234 to the stock price.

Dose this operation have some realistic meanings?

Thanks

No, -1234 is just a special value which means the data is missing. You can replace it with any negative number that is large enough.
