i don't see any buy or sell orders/any kind of order chart history like in coinsecure.in???
There are 2 types of exchanges.
C2C = Customer to Customer exchange, Eg : Btc-e, Cryptsy, Coinsecure etc
and then there are the other kind of exchange, which I think is called M2C = Merchant to Customer exchange.
Basically these type of exchanges dont rely on the price of the sell orders listed by the customers but rather have a predetermined buy/sell rate based on some market parameters.
Unocoin falls in the second category. I operated a similar form of forum exchange a year ago here in the forums.
There is also another type, which is a platform only and do not touch FIAT, e.g. localbitcoins.
