I am especially fond of trading the YM e-mini contract which often entails trading with fewer professional traders and more low-volume retail traders, especially when compared with trading on the ES contract. This is not to say, of course, that there are no professional traders on the YM e-mini contract, because there are numerous professional traders on the YM. On the other hand, there are periods of time when trading is dominated by smaller retail traders who trade in contract lots of one or two contracts. Most traders who trade the YM on a consistent basis are aware of the tendency of smaller e-mini traders to take long positions during the lunch break. This time of day is often referred to as the “stand down” period.
I was recently at a seminar related to trading and listened to one professional trader who explained that she never took a short position between 11:30 AM CST and 12:30 PM CST. Why? During this period of time most of the professional traders are on the sidelines with lunch or other duties and the trading is dominated by retail traders. While the correlation is not 100%, it is usually the case that the market will rise as the smaller traders take over the trading action on the YM contract.
I tend to agree with the woman at the seminar, as I have watched time and again the market slowly rise over the lunch time. This can happen when the market has been moving downward throughout the course of the morning or if the market has been moving upward. For whatever reason, retail investors tend to take long positions at a surprising frequency. There must be some explanation for this phenomenon, and I have looked at this tendency for many years and have yet to understand exactly why it occurs. I have my theories on this topic, but they are little more than speculation and not worthy of mentioning without empirical evidence. On the other hand, I have had more occasions than I care to admit in my career where a short trade was initiated at 10:30 AM CST and the trade failed to move in the direction I intended and the trade lapsed into the lunchtime. To my dismay, I have generally watched my trade disintegrate as the market slowly drifted upwards during this period of time. I have come to refer to this market action is a “death by 1000 paper cuts”, as there is no dramatic movement during the lunch hour, just a slow drift to the upside that eventually hits your stop loss, if you allow it to.
I should point out that there must be a group of retail traders who are comfortable selling to the short side, as it is improbable that all small traders are of the same mindset. But I would advise most traders to heed my warning; and that is to avoid short trading when smaller retail traders are in control of the market.
I will point out that I have no widespread empirical evidence to support my claim (though there are some lesser studies supporting this observation), just years of observation and conversations with fellow traders who are of the same mindset. A casual review of trading chart groupings from the last 45 days brought a smile to my face though; on nearly 75% of those trading days the market drifted upwards over the lunchtime. On the other hand, I have seen very little written on this topic and the evidence must be anecdotal; but experienced traders, by and large, are in general agreement on this topic. Avoid short trading over the lunch hour.
In summary, I have described a tendency of the market to slowly rise over the lunch hour. I have also pointed out that it is not necessarily wise to initiate short positions during this period. Finally, I have pointed out that there has been little empirical evidence to substantiate this position, but I am well aware that my beliefs are a widely held maxim among professional traders. I recommend observing this phenomenon for yourself over a period of time. You will be surprised at the outcome of your observations, and quite possibly be bewildered. Nonetheless, it is no secret among professional traders that the lunch hour is a treacherous time to be on the short side of the YM contract.
