Who is controlling our market

I have just enetred the market, and i am a novice.

But seeing the market crash successive days close to Rs 100000000000
gave me a feeling that we r still not totally independent and free to function;
and that outside forces still controll us inspite of what we saw when
IPO of Reliance Power recently was floated.

I am hearing for the last one year that our economy is most robust in the world.

I will apreciate if any one in our fraternity of small investors, throw some light
in simple words, how this all has happened.
And have plan for the future to incorporate an alarm in our investment
startegy, so that major chunk of our investment is squared up leaving a small
amount to be in the market to flow with the trend.

So that impact this great is avoided.

Thanks and Best Regards.

Happy investing for the future.
