I came across this automatically refreshing Nifty Intra charting with various information which are quite useful during intraday trading. I have put it permanently in the blog at the top as "Nifty Intraday charting".
Before you begin to use it, study the Nifty internals and go in with a plan and use this wonderful intra charting.
My plan was..Nifty already overbought will become highly overbought due to a gap up for the RBI actions and hence would give a sell and so I bought a PUT. and covered the same for a small profit. As the daily trend is up & the hourly has not given any firm sell, I bought a call around 2.00 PM and booked out of it by 3.10 PM. and the intra charts did help a lot.(Though I have my own intracharts..but constructing it continuously is quite tedious but this one is a fully baked cake with icing & all).
Nothing in the world can give you a foolproof system. But this one is quite useful. Put to test for a while & then follow it.
