1. Supply coming in: up bar wide spread with high-ultra high volume closing off the highs of the bar follow by a down bar that confirms this weakness (2). 3. No demand bar: up bar with average-wide spread closing off the highs with less volume than the previous 3 bars, this signal needs to be confirmed with a down bar. 4. Trap up move: down bar with super wide spread, clossing off the lows with high volume, may some demand enter in this bar, but you will know it if the next bar closes high. 5. Gotcha bar: down bar with ultra wide spread, closing at the lows or near the lows of the bar with ultra high volume, this bar confirms the weakness of the previous bar, and, confirm the weakness of the sequencial of 1 and 3 signals. 6. Stopping volume: up bar closin at the highs or near the highs with high-ultra high volume, this bar confirms that may there is some demand in the previous bar, but you need confirmation. 7. Supply coming in: down bar closing on the lows of the bar, with high volume. This bar says: if there is some demand in the previous bar, why i close at the lows? because the market is weak. 8-9. Test's: down bars with average-narrow spread closing at the lows-near the lows with volume less than the previous 5 bars. The second test is seeing after a gap so if it confirms, may we have some demand in the market. (The next bar is up but with low volume, so, the tests doesnt confirm). 10. Up-thrust. Down bar that is marked up at the beginning of the bar to close down, average-wide spread with average volume, this confirms the weakness of the failed test (9). 11. Up-thrust (my favorite in this chart). Down bar that is marked up at the beginning of the bar to close down, average-wide spread with average volume, this bar confirms that the market even in over-sold state, will not go up because there is weakness. This signal is seen in a zone of previous weakness (signals 5, 8-9, 10) so you can assume that the market will not go up until demand in form of test's or no supply-shake out take place. 12. Bottoms reversal. Down bar, ultra high-volume, wide spread closing at or near the lows followed by a up bar wide spread closing at or near the highs confirms demand in the previous bar (the down bar). This signal need confirmation (up bar with average-high volume) but how can see, the next bar is a narrow spread bar with volume less than the previous 5-6 bars. 13. Test. down bars with average-narrow spread closing at the lows-near the lows with volume less than the previous 2 bars. 14. Potentional climatic action or gotcha bar. Down bar with wide spread closing at the lows with ultra high volume. This bar take place and closes lower than all of the bar seen before it. So you can assume that if the next bar is down, this bar shows that smart money is selling.
To take a short trade: wait until the next bar closes, if this closes down (for the time of now, the bar looks like a up-thrust, that is a signal to go short) and it breaks the support line of the previous bar, you can scalp or trade in this timeframe to the short side.
I prefer to scalp the market when i see a up thrust, no demand, supply coming in after the breakout of the support line.
