but main problem is that i don't know how to parse this data and how to know that what is the meaning of characters and how to convert this data in to useful manner , i have read out NSE document which tells that first char is tells data is compressed or not but i don't know that which of these is first and last, If any one can understand my problem and experience in these type of application please help me and suggest what i have to do so understand this string

Thanks

1. DON'T SHOUT!
2. What data? How can anyone help you parse something unless you give some idea of the format it is in.

Sorry ! I received the data as an array of bytes using UDP from NSE broad cast(National Stock Exchange).After that I have to decompress it using the LZO library. I have already that library and I am able to decompress that data. But after that I dont know how to parse that decompress data.
