The  Doji

It represents indecision. You have an open, with movement both above and below the open in the case of yesterday's Doji (marked with red arrows), with a close right at the open. It looks like a plus sign.

In general the Doji is a reversal bar, signifying the end of a trend run, in this case up-trend Wave 2. But other times they are just neutral, indecision. It depends on where it occurs.  A 'Gravestone Doji' where the cross was nearer the bottom is a more bearish trend reversal indicator. But as yesterday's Doji comes after a long trend run (100%) and at a key resistance point, it is more likely a reversal indicator.

Notice also that today's red bar is what is called an 'Inside Day / Inside Bar', that is to say all the action is inside the previous bar. That is also a form of indecision, with no urge to make a higher high or a lower low than the previous day, but also suggests trend-reversal like the Doji.

Note also that today's inside bar therefore has the appearance of a coil, it needs to resolve in either direction. Without a lower low, we will instead be looking for a continuation of the rally. But as it closed a bit below Key Resistance and in general signals reversal, in the absence of a PR/News/Rumour trigger, we should see a pullback.

Notice that there was another CTIX Doji reversal bar on 10/25/12 which exactly signified the end to the trend run down from the original move to $1.18, and started the rally Wave 1. This called a 'Dragonfly Doji' The open and close were at the high of the day, and all the action below was rejected. (marked with a blue arrow) The next day was a 'Hammer", which further indicated that the Dragonfly Doji signaled a trend reversal and a market low.
