Why Use Trading Rules?
In order to successfully trade gapping stocks, one should use a disciplined set of entry and exit rules to signal trades and minimize risk. Additionally, gap trading strategies can be applied to weekly, end-of-day or intraday gaps. It is important for longer-term investors to understand the mechanics of gaps, as 'short' signals can be used as exit signals to sell holdings.
Each of the four gap types has a long and short trading signal, defining the eight gap trading strategies. The basic tenet of gap trading is to allow one hour after the market opens for the stock price to establish its range. A Modified Trading Method, to be discussed later, can be used with any of the eight primary strategies to trigger trades before the first hour, although it involves more risk. Once a position is entered, you calculate and set an 8% trailing stop to exit a long position, and a 4% trailing stop to exit a short position. A trailing stop is simply an exit threshold that follows the rising price or falling price in the case of short positions.
Long Example: You buy a stock at $100. You set the exit at no more than 8% below that, or $92. If the price rises to $120, you raise the stop to $110.375, which is approximately 8% below $120. The stop keeps rising as long as the stock price rises. In this manner, you follow the rise in stock price with either a real or mental stop that is executed when the price trend finally reverses.
Short Example: You short a stock at $100. You set the Buy-to-Cover at $104 so that a trend reversal of 4% would force you to exit the position. If the price drops to $90, you recalculate the stop at 4% above that number, or $93 to Buy-to-Cover.
The eight primary strategies are as follows:
Full Gap Up: Long
If a stock's opening price is greater than yesterday's high, revisit the 1-minute chart after 10:30 AM and set a long (buy) stop two ticks above the high achieved in the first hour of trading. (Note: A 'tick' is defined as the bid/ask spread, usually 1/8 to 1/4 point, depending on the stock.)
Full Gap Up: Short
If the stock gaps up, but there is insufficient buying pressure to sustain the rise, the stock price will level or drop below the opening gap price. Traders can set similar entry signals for short positions as follows:
If a stock's opening price is greater than yesterday's high, revisit the 1-minute chart after 10:30 AM and set a short stop equal to two ticks below the low achieved in the first hour of trading.
Full Gap Down: Long
Poor earnings, bad news, organizational changes and market influences can cause a stock's price to drop uncharacteristically. A full gap down occurs when the price is below not only the previous day's close but the low of the day before as well. A stock whose price opens in a full gap down, then begins to climb immediately, is known as a “Dead Cat Bounce.”
If a stock's opening price is less than yesterday's low, set a long stop equal to two ticks more than yesterday's low.
Full Gap Down: Short
If a stock's opening price is less than yesterday's low, revisit the 1-minute chart after 10:30 AM and set a short stop equal to two ticks below the low achieved in the first hour of trading.
The difference between a Full and Partial Gap is risk and potential gain. In general, a stock gapping completely above the previous day's high has a significant change in the market's desire to own or sell it. Demand is large enough to force the market maker or floor specialist to make a major price change to accommodate the unfilled orders. Full gapping stocks generally trend farther in one direction than stocks which only partially gap. However, a smaller demand may just require the trading floor to only move price above or below the previous close in order to trigger buying or selling to fill on-hand orders. There is a generally a greater opportunity for gain over several days in full gapping stocks.
If there is not enough interest in selling or buying a stock after the initial orders are filled, the stock will return to its trading range quickly. Entering a trade for a partially gapping stock generally calls for either greater attention or closer trailing stops of 5-6%.
Forex trading Signals
Partial Gap Up: Long
If a stock's opening price is greater than yesterday's close, but not greater than yesterday's high, the condition is considered a Partial Gap Up. The process for a long entry is the same as for Full Gaps, in that one revisits the 1-minute chart after 10:30 AM and sets a long (buy) stop two ticks above the high achieved in the first hour of trading.
Partial Gap Up: Short
The short trade process for a partial gap up is the same as for Full Gaps, in that one revisits the 1-minute chart after 10:30 AM and sets a short stop two ticks below the low achieved in the first hour of trading.
