The Bow Tie
The Bow Tie formation is formed by the interplay of two or three moving averages. These averages must be dissimilar in time periods employed to the point that clear crossings are evident. For example 20-day and 10-day moving averages will work well but 20-day and 15-day moving averages would be less effective. In the case of a three average set, 5,10 and 20 day averages would be appropriate. For even more defined visual expressions the moving averages could be spread out further such as 7, 30 and 100-day averages. You can see these type of patterns typically after wave two in the longer term Elliott wave technique or after wave 4. Wave b can also cause this. While the Bow Tie and Butterfly formations are not part of the Elliott wave theories, it's good to understand the chart patterns in terms of larger strategies or techniques .
The underlying principle is that traders want to recognize a new trend relatively early in the life span of that trend. Moving averages provide clear lines of demarcation. With two or three moving averages on the same chart we are able to use these lines of demarcation to our advantage. These averages will also demonstrate congestion or consolidation, which may herald the emergence of a new trend.
Bow Ties are formed as the shorter moving average crosses the longer moving average at such an angle as to form what appears to be a bow tie or a butterfly. This requires the short moving average angle to continue after the crossing much as it was just prior. Using three moving averages helps to illustrate consolidation in a definable way. This variation of the Bow Tie is formed, as the three moving averages appear to lie on top of one another for a period of days and then break apart. These signals are often quite strong. The trade would be taken in the direction of the shortest moving average after it breaks away from the others, thus forming the second wing of the bow tie.
