2. Interesting that you bought this up..
.. Everyone keeps blaming brokers in general, but it is usually clients who default a lot more than the brokers.. ot all clients, but quite a few of them will stop picking up calls the day the account goes into debit. When gold hit circuit recently apparently 5% of all MCX members wend down because of client defaults.
At Zerodha we give conservative leverages, avoid giving leverages on days when news expected, we do whatever possible in control. Leverage is what kills a trader and the broker..
..
That said, if the account goes to debit and if the client doesn't respond, we have a system to take legal action. Our lawyers send a notice and the process starts.
What is also interesting is that the member associations are working towards creating a database of default clients and similar to how it works in say credit card business, if a client has defaulted, if he goes to open an account with another broker, he will get to know that he is a client who has defaulted and won't let him open an account.. A system like this is required for brokers, because something that a lot of people don't know about is that client defaults can bring the revenue down by as much as 20% for a brokerage business..There have been such cases with a few listed firms in the past..
