The Psychology Behind Round Numbers and Support Resistance Levels in Futures Trading - NeuroStreet Inc.

Have you ever wondered why prices tend to stall at certain levels in the futures market? Is this just a coincidence or is there a valid reason behind this happening? Well, this phenomenon may be explained based on the psychology of futures traders.

As humans, we tend to think in terms of whole, round numbers rather than in terms of uneven random numbers. This happens very regularly in everyday life where numbers tend to be rounded up or down to simplify things.

For example, if someone asked you the time and you looked at your watch and it was 12:29pm, what time would you give the person? Based on the psychology of rounding, many people are likely to just say 12:30pm rather than 12:29pm since 12:30pm is a rounded number and 12:29 is not.

Or what if you wanted to know the price of a meal and saw that it was advertised for $9.99? In your mind, you would probably round it up to $10 instead of $9.99. A similar thing happens in trading when traders conduct technical analysis by examining the price charts.

Futures Trading and Round Numbers

By default, most traders tend to prefer rounded currency values to odd, random values. Because of this psychology, areas of support and resistance tend to form around certain price levels since traders subconsciously tend to place stops and take profits at areas where price is rounded. For example, a trader is more likely to place a stop at the 1.2500 level than at the 1.2502 level.


Increments of 100 and 50

In futures trading, rounded prices usually are regarded as those prices in which there are double zeroes (or more) at the end of the price e.g. 1.3400 or 1.5000. Usually the more zeroes at the end of the price, the stronger psychological level and barrier. In addition, short-term intraday traders also view half way points and price points that are multiples of 100 to be rounded.

If you were to study any price chart, you would find that areas of resistance and support usually form at these price levels. Price swings tend to take place at these resistance and support levels.

Once the price crosses these invisible barriers, the price changes from being a level of support to be a level of resistance or from being a level of resistance to a level of support. Traders often use these signals as an indication of what is likely to happen once price approaches these psychological levels. 

If price tended to stall at these levels when prices were going up, then chances are great that they will stall at that same price, should the price reverse and fall.

In the case below, as price approaches $69.50 for a second and third time the price is rejected.

How Support and Resistance Psychology Can Improve Your Trading Success Rate

Support and resistance levels tend to hold true until or unless there is a breakout. Therefore, traders can use these levels to predict how prices are likely to move with a high degree of accuracy.

In addition, these levels help traders to establish where they should naturally place their stop loss and take profit orders. A stop loss order is usually placed a few ticks below a level of support or a few ticks above a level of resistance. Or a profit target order is usually placed a few ticks below a level of resistance or a few ticks above a level of support. Since most traders tend to trade this way, you will find that price action tends to follow these patterns very closely.

For some traders, the first thing that they do when deciding how to trade, is to draw in major lines of support and major lines of resistance. These lines act as guides to help the trader determine the most likely direction that the market will take. In many cases, these “prophecies” tend to become self-fulfilled.



Traders value simplicity and therefore tend to push prices towards areas where prices are rounded. This creates areas of resistance and areas of support at which prices tend to stall. Prices will continue to stall at these prices unless there is a breakout and the market sentiment changes.

In such an event, a previous support level would become a resistance level and a previous resistance level would become a support level.

These levels of support and resistance can help traders to more accurately predict the movement of prices. This means that resistance and support can help traders to earn more profits and to make better trading decisions.
