At first glance it looks like an ascending triangle which favours a breakout to the upside. I then noticed you haven't drawn the slope to connect the majority of low points, more of a casual lowest low on chart to most recent low, which doesn't really have any technical basis.
What is bullish about this is that the lows are higher. What do I know? I don't trade the ftse and my chart reading and technical analysis is dreadful. But if I were going to waste yet more money trading stuff I don't understand, I'd be lining up with a buy limit just above 6900.
Yes, but T333 is right that sellers do not "control" the market in such circumstances. It is buyers who are in control and who force sellers to offer lower and lower before they will buy. ie: a buyers market.
