The chart to go with that trade and some further explanation.
NXTL opened at 28.45, fell rapidly in the first few seconds, then my reading of the tape and level 2 showed the buying power as it surged back up so my entry was on the button at 28.45.
It hesitated at 28.75, rose and then fell back to the same level.
The behaviour there was enough for me to grab what the market offered and take a quick "scalp".
For me that 28.75 showed some significance on a micro level and the stock remained on my radar.
The chart doesn't really show much at the time of the trades - the fact is that chart understanding is a lot more than you can read in any book or on any web site - it is tied up inextricably with what is happening on the micro level and being able to read that properly. The only ways to get to that degree of understanding are, imho, to be taught and then get plenty of practice afterwards before trading or to literally spend years trying to figure it out for yourself.
What is particularly interesting on this chart is that precise balancing point of the interaction of buyer and sellers I identified at 28.75 proved significant later as support and resistance.
