On Friday, I noticed a bunch of buyers, trying hard to take nifty up, key levels I marked for monday are 22720 and 22600 in Nifty Future. So above 22720, I will look for buy, below 22600 I will look only for sell and in between a ping pong but still I will have a buying bias based on live OFA in 22720-22600.
On the contrary, right at opening, I will look for a Sell trade for some points as I believe, market will play a dirty game at start, also I will stop trading once I earn a respectable figure.
