The first set of support and resistance trendlines are the internal parallel diagonal trendlines within the channel. These have been important as you can easily see.
The second set of trendlines have been even more important so far however, and they are the horizontal trendlines that I have marked in red within the channel. These give very useful entry and exit levels for short term trades as they have been extremely good in establishing horizontal trading channels within the main rising channel.
Once a new horizontal support/resistance channel has been established, it is rarely broken. You can see that only one level has been broken so far, and that was at the touch of the bottom channel trendline on Monday. Once broken on the way up, these then act as an effective support floor until the next horizontal support/resistance level up has been broken.
As for the current channel, it was established yesterday with a ceiling at 1165.5, having risen straight through an intermediate channel on the way, which has happened once before lower down. The floor of the new horizontal trading channel was therefore unconfirmed until we had a spike down near the close to confirm it, and I drew the new floor level then and posted it in various places. You can see that the floor was tested again overnight and was effective support.
A couple of further points about the main rising ES channel are worth noting.
Firstly, the bottom trendline of the channel is now at 1153. If that is broken with confidence then the rising channel will finally be broken, and a significant interim top is likely to have been made. That breach would have to be sustained until the end of the trading hour, as this is an hourly chart, and both the top and bottom trendlines on the channel has been breached for short periods before within a trading hour, so a break below that was not sustained would not be a definitive break until the end of the trading hour.
Secondly, the last touch of an outer trendline on this channel was at the bottom trendline, and we should not expect that the bottom trendline will be touched again before the top trendline, currently at 1176, is touched first. A touch of the bottom trendline again before that happens would be a part-rise and a strong signal that the channel is likely to break downwards. By no means would that be a certainty until it does break, but that will give a useful signal that it is time to consider repositioning short.
That said, the obvious short term trade there would still be to go long, as the risk/reward for a long there with with a stop four points below would be so high that it would be a good trade in any case. Definitely a trade to use a tight stop though.
