Corrective Wave type Pattern

This was the clue that we might be in a corrective wave. The market retraced after the 3 waves up into the 1247.50 high. Look for test of low. This would be opportunity to buy, expecting the low of 1234.75 to hold based on higher timeframe charts showing support for now. Upside targets: 1243.75 to test of 1247.50 before moving down. IF I believe that we are in a corrective mode for more down, THEN, I have to be looking for a JOT pattern to enter ss to ride this down to lower lows. However, the 120min chart shows up with no ss signal.
