Stock exchanges earn major share of their profit from processing the orders.

They just lost at least a whole day of revenue.

After compiling some number for their annual report[1], I would say the loss from TSE revenue alone is roughly 2 million USD. But considering the effect trickling down the revenue stream where other security partners whose revenue depends on earning transaction fees, I would say the real damage would be many folds of that 2 million loss from TSE.

More or less by definition, this won't impact their yearly bottom line by more than 0.3% (at least to within first order). Which is quite a bit, but it still seems super minor. Just like 2 million. Isn't that peanuts for a stock exchange?

Agreed that 2 million USD is not much compared to total revenue.

However, you see, TSE YoY growth from 2017 to 2018 is roughly 4 million USD. Growth is hard as it is for TSE, leaving money on the table like this time definitely hurts.
