Thanks to mt4trader for starting this interesting thread.
There are lots and lots of tools that are available for using Order Flow in Trading. But we need to have a data feed that provides proper TICK Data with Bid and Ask Info. Order Flow Analysis cannot be done on Minute Data. For Indian Markets, Esignal is one such vendor who provides tick data and is compatible with a lot of platforms.
MarketDelta is a pioneer in the field of Order Flow Analysis. They invented the Footprint Charts and their whole platform is built around OFA. Later on, more and more vendors jumped in and created plug-ins which provide the OFA capability in many other famous trading platforms. You can check about MarketDelta from this link -

Spend some time on their blog and watch out their videos, they explain Order Flow in detail.

Ninja Trader also supports OFA and it has got a great Eco System, where you can check out various add-Ons etc. In the left hand side pane, choose Indicator Category and then select - Order Flow / Tape Reading option and it will show you a lot of vendors which provide Order Flow Tools -
