There is no point at all in discussing these things again and again as long as the watch dog realise the following fact.
1-Though we got indepedence in 1947 , we didnt get any idepedence till now regarding the ruling related to financial fraud, manipulation and domination related to stock market and our currency.All are under the full control of western forces and they will keep on doing these things laughing at our authorities because of the folowing reason
our market open prior to indian opening (the first chance to manipulate the indian market by doing some cross trading those who group who create large position in indian market,else fool the indian traders after manipulating the market after trading hours, so the purpose of sgx nifty is nothing but an advantage given for overseas traders to rule indian market , same like how british ruled india before independance..We are slaves to them..realise this naked truth.
2-The next fraud game happen in the pre opening where a seperate window is created prior to the official opening and all circular trade enter in to adjustment trading before market opening..Also this time period is used to fix the opening of the nifty.so with least effort market can be controlled by a group of people.If market open with out pre opening, then prior fixing is not so easy.So the smart people who created the pre opening session to help these players from outside who are Exchange traded fund and some FII who work hand in hand with some operators inside our market..
so when all these people join their hand, and when the political parties provide all prior information from the finance ministry , the job is so easy to do.
3-The last one is the speed game using the High frequency software which generate trade in 1/1000 seconds and cancell more than 70% of the orders which is called spoofing which though my law is not permitted in indian market, but as long There are many tools to hide such trade from the official checking, the authorities cant find anything.Those who do the fraud are well equipped with their tools and no one can touch them.
In europe some countries already stopped this practice and recently European union fined 5 billions. see the report below link.
but in india the game is going on in another form and they are sure that nothing is going to happen in india, as india fear of dollar outflow.Else they threaten india using their rating agencies.
Until and unless all are treated equally regarding the speed of the order entry, Sebi cant win the confidence of the public and investors.
