The month of May had a significantly higher daily volatility. On average, the ES E-Mini has a daily range from low to high of 1.6% In May, this averaged 2.8% This means that after the open buy or sell of a trade, there is a high probability that the stop loss will also be hit.

Furthermore, on many trading days, we saw that the futures immediately chose a specific direction from the opening. The trading method of the model portfolio is based on the fact that, on average, there is always some counter-movement intraday. In anticipation of that small counter-movement, a limit order is placed, but that opportunity thus occurred less frequently. The only signal that was sent had a limit price which unfortunately was not hit.
