Hi PT,
I do not think it is "Tukka". You are very good at numbers.
You decide on stoploss & resistance level. I do not know how but would like to know more on this. which ever data refered by you.
I was also observing this put but got firm signal when 10min avg crossed 20min avg from top. But till this time Put was costing 50. (Which you estimated when it was 35). you hold it eventhough it went to 30. So you worked with some calculations which has given you inputs that market is going to fall.
