In general, most gap ups and downs typically occur due to a catalyst or support/resistance area where hedge funds are stepping in to control the overall direction of the market. Generally speaking, here are some facts and my thoughts on playing gaps.
91.4% Gap Ups/Gap Downs will eventually be filled
Gaps represent unsettled areas (supply and demand) within the market
Gaps are formed when a large number of buyers or sellers control the aftermarket and/or premarket (Daily timeframe)
Due to the one sided and unexpected move, the market wants to determine whether the zone is truly for buyers or sellers
With no clear level of buyers and sellers, price action can be quick within gaps and they can fill very quickly.
Gaps sometimes takes days, weeks, months, or years before they fill. In some cases, gaps may only partially fill and not be completed until some time later/if ever.
Below are two major ways to play Gap Ups and Gap Downs
Learn why GAP Ups and GAP Downs occur
Bag holding (when price moves below your purchase price and you hold)
DAILY CHART EXAMPLE - SQUARE
Wait for your Opening candle. If you are playing the daily chart, wait one day, if you are playing the 10 minute charts wait 10 minutes.
Determine your midpoint
Gap Ups = (Opening of New Day - Close of Previous Day) and divide by two (2)
Gap Downs = (Close of Previous Day - Opening of New Day) and divide by two (2)
The midpoint often can serve as resistance
Wait for Opening Candle
Swing Trading (Daily Candles) - Wait one day
Intraday Trading - First candle (10MIN, 15MIN, 30MIN, 1HR); prefer 30MIN to 11HR
Based on Opening Price, determine if it is going up or down
Green Candle: Opening is now your key support area. This can be used for pullbacks, but exit below this point.
Red candle forms: High is resistance level to watch for rise above, otherwise play short, puts, or wait until rise above. Play as a Gap Down: look for midpoint as first target to capture profits.
This strategy uses the previous candles to determine strength of gap movement or rejection
Note how after the drop the market fills the short gap to the open of green candle (note the dotted white line)
After price is rejected, you can enter anytime after rejection, but I would select the open of the day as it breaks back down.
Based on this example you could have held throughout the entire day or at least sold some at the 394 target (low of previous green candle)
Use the previous candles as price targets.
When in a reversal, avoid entering on gaps.
Doji or Spinning Top
You are in a bearish market and you are at the potential beginning of a reversal
If we see a gap up from a doji or spinning top, I am holding and waiting for the following candle as indicated in the above section
Continuation candle that closes above doji, spinning top, or hammer
We could have already entered based upon our candle rising above the doji, spinning top, or hammer
In many cases, you will have a gap fill down and it will retrace the move since there was a gap up overnight, most likely from shorts closing their position and other shorts stepping in again
Taking Profits
You can stay long and wait for a breakdown on a lower time frame to sell (30 min/1hour)
Additionally, we can simply hold through our position until the gap fill, if it is not too far away, and to see if it bounces
Worst case scenario is that we are back to where we entered or our profit from the previous day
