Breakout Imminent ?

Here is a five minute bar chart of the cash S&P 500 index. You can see that the market has built a base are over the past five trading days. A move above 780 on this chart on reasonably high volume would for that reason be very bullish and this is what I expect to happen later today or tomorrow. First stop after that would be resistance at 790 and the next subsequent resistance will be found near 820.
