Reasons for telling long,
1. check the estimate vs actual and after effects of price, this time it ll post lower than estimate.
2. it is in trend line support for short term and dropped from resistance trend line of medium term, hence if bounce confirmed i.e if goes above 535 zone marked in trend (tats why only for aggresive trader, defensive trader can wait for confirmation) it ll sure shot go for medium term uptrend which is very gud risk: reward ratio.
3. FIIs started buying and hence lots of chance of uptrend.
failure of this idea will be confirmed only after results if it falls below 500 (for those who have confident and big target) or below 518 for defensive aggressor.
