Lots of Hammers in the averages

A Candlestcick Hammer is a bullish reversal pattern, it shows lower prices were tested and rejected, it look like we'll close with these hammers, many after having taken out support levels making them higher probability and if the move comes off, more explosive as shorts would be squeezed.

 QQQ hammer after taking out major support and closing above it (thus far).

 DIA, a VERY long legged hammer on increasing volume

 SPY hammer and some former hammers, this one took out support and closed back above it.

IWM hammer, again took out support and closed back above it, this in its simplest form is a rejection of lower prices and a new support level.
