Hi John. Not a coach at all, just a student of Kyle's. Using that green candle you have makes perfect sense, as it is where the downward move originated, I would just extend the block down to cover the low of that next red candle (to the right) since they are so close, looks like just a tick or so. The main move happens after that, implying that those 2 candles were where the block of orders occurred that caused the move. More importantly, I would be sure to cover that recent high a couple candles back in your block as well. That would match right up to how you have demand drawn, which looks great, there are just some in between candles for supply.
