So you are saying that you watch every day but don't take a trade every day?
In your initial post you showed a 2 pt trade. Two pts does not seem like a 'trend' trade: I would consider it a scalp. What is your stop-loss on your trades?
I prefer to trade in trend days and target 2 points that's why I have a very high winning rates. Plus once or twice a month I manage to capture the trend and earn big (10 - 20 pts).
I watch the chart every day for 30 mins after those 30 mins I know if I will trade or not. Also I know the exact entry and exit prices 5 mins after the market opens.
The envelope is just a secondary confirmation tool. I watch the ADV/DEC chart the first 30 mins of the day if it's not moving strong enough then I wont trade
If it hits the marks then I am good to trade.
