Does anyone know whether the insurance provided by SIPC covers short sell proceeds kept by a brokerage company such as IBKR? I know IBKR will pay some interest on the short sell proceeds kept in the brokerage account but I am not sure if it means it is counted as an asset covered by SIPC. If...

Thanks for sharing your experience. It answers many questions I have in mind for long.

Would you mind explaining a little more about what KCIX does? I browsed its website but still couldn't figure out how it is related with trading use. The list looks probably what I am looking for. Thanks!

I've been curious about the relative lack of exchange-traded debts (ETD) compared to dealer-sold bonds, particularly in the corporate market. While some bonds go to exchanges (only about 180~200 issues), the vast majority are sold through dealers. I thought that the transparency and reporting...

I'm in the process of looking for colocation services in Equinix NY4 or NY5 datacenters for my business. I'm hoping to get some recommendations from the community on which hosting service providers offer these services and at what costs. If you have any experience with colocation or dedicated...

I'm also curious about the reason for the difference in regulations between equity...

I recently came across a condition in Interactive Brokers' agreement that states clients cannot have market making trading behavior in US equity options. The condition looks very strict. I'm curious about the legality of this condition and whether there have been any challenges or discussions...

Thanks for Tessa's explanation. This is great news for me. Would you mind sharing an example of where we can find a venue's policy on redistributing historical data? I did find an academic paper, "Understanding the market for US equity market data" by Charles M. Jones that makes the same claim...

If I collect market data from some third party (such as brokers or some service API) and redistribute the data with others (could be for profits or non-profit), do I need to get licensing from exchanges? I am thinking about a project to build something like wikipedia for market data where...

Thanks! It is a example to remind us of the limitation of mathematical approximation. As I mentioned before, Markowitz's theory is valid if return is not distributed too widely, e.g. interval (-40%, 50%). The example with 100% loss with 1% probability is out of reach of Markowitz's theory...
