They screw their customers atleast once every month with technical glitches resulting in huge loss for the day traders,who are their major customers..and they are never sorry about it.
The underlying infrastructure in the Indian capital markets is very constrained and was not really built for the kind of scale we're operating at in 2020. The next biggest broker processes only a fraction of our daily volumes. So it really is a matter of scale, industry wide.
To give you an example, the leased lines NSE (National Stock Exchange) offers to brokers to send orders take up to four months to commission, and each line has a max capacity of 1000 messages / second. We've been processing close to 8 million trades a day. So you can imagine how painful things can be.
We've been working hard over the years to reduce legacy market infrastructure dependencies and have been making significant progress.
You're processing an average of 1.33 million trades/hour. Let's double that and round up for peak traffic, that's 3 million trades/hour or 833.33 trades/second.
Unless I'm missing something, you only need 1 line. What's the problem here?
