Friends I am not talking in favour of the broker, but please understand that as you mentioned that one has to pay (or lose money) for their mistake, then RKSV has already lost money. Their business is brokerage revenue by offering services, they have already lost one hour of brokerage revenue which will not be compensated by any means and by any one. Their fixed overhead remain the same in this lost one hour. Also the goodwill (which is more important than money, atleast in the service oriented industry) is hit which is where it will hurt them the most.
Also most of the traders feel that they would have made a killing only when there is some issue like this. It is like they would have never taken a wrong trade in this lost time. Which is unlikely, on the contrary there could have been traders who would make money just sheerly hold this position compulsarily during this period, which they would have other exited early with lesser profits.
In my opinion we should treat this just like we tread gap openings. We take risk of gaps by holding overnight positions. So we can think this a extend opening time.
My only suggestion to RKSV is they need to immediately communicate this to all their clients. And ideally this should be done premarket opening. E.g. we have successfully done migration/ upgradation OR though the testing has been done, the successful upgradation will be known only after market opening and confirmation would be sent accordingly etc...etc, OR we may face issues after this upgradation/migration and we will keep you informed, OR you can visit this link xxxxxx on our website for latest updates related to this upgradation / migration etc.
They should not treat this issue as if it were a news to them too after the market opened. As this is what it appears to us now. This doesnt reflect professionalism on their part in anyways.
