Sir,
Intraday data will increase the size of data base very rapidly ,reducing the speed of QS, and we need not keep more than one month,s intraday data in data base.So

a facility to DELETE INTRA DAY DATA BEFORE A CERTAIN DATE is desirable

If I may offer a suggestion, rather than removing data before a fixed date it mght be more convenient to express that as a span. That is, for example, "keep the most recent 100 bars/days/monts". That avoids having to remember to update the cutoff date every so often. Database size would remain nearly constant.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
