This article is going to be an extension of a previous article where we performed an intraday price study. We do this by exploring different market sessions to determine if we can find an edge for a possible intraday trading system. If you have not read the previous article, When To Go Long, I urge you to read this because we are going to jump right in and explore the same concept on the short side.
As a reminder here are the five different market sessions we will be looking at.
BEAR MARKET: We will only open our short trade when price is trading below the 200-day SMA. Below is a bar graph representing the average profit per trade for each period. Period 1 starts on the left-hand side through period 5 on the far right-hand side. During a bear market there seems to be not much of an edge. Sure the last two sessions, The Close session and the Post-Market session, show the most profit, but it’s not much.
Winner: None? Sessions 1, 4 and 5 are hardly above zero.
BULL MARKET: Now I will reverse the regime filter so we will be shorting during a bull market. That is, we will be opening new trades when the price is trading above the 200-day simple moving average. Below is a bar graph representing the average profit per trade for each period. What this shows is during a bull market there is an edge with shorting during the Close and Post-Market sessions.
Winner: Both the The Close and Post-Market.
BEAR MARKET: Now I will test our mean-reversion trading system rules over the five different periods. Below is a bar graph representing the average profit per trade for each period. The only session which is positive is during the Post-Market session. So for most of the sessions, short during a bear market is not profitable.
Winner: Pre-Market Session
BULL MARKET: Let’s now look at our mean-reversion trading strategy during a bull market. Below is a bar graph representing the average profit per trade for each period. Here there are three possible sessions which show positive returns. Those are Pre-Market, Midday, and Post-Market sessions. Strange how shoring during a bull market is producing more sessions which make money.
Winner: Pre-Market, Midday, and Post-Market
The graph below may look a little confusing at first. Focus on the bars above the zero line that show the most average profit per trade. Ask yourself, which bars are the largest? Notice the blue bar for session 5 (Post-Market) is the largest. This group is our trend following system during a bear market. It says that shorting after the close when we already have falling momentum is likely to be profitable.
The next two largest bars are colored yellow. Those are the mean-reversion systems during Pre-Market and Midday. During these times shorting might be profitable when using a mean reverting type strategy.
If you’re looking to create an intraday trend following system there are two possible choices for further exploration:
If you’re looking to create an intraday mean reverting system there are several possible choices for further exploration:
Remember, both the trend following and mean reverting strategies presented here are not viable trading systems as they currently stand. You simply can’t expect these simple trading strategies to produce results with real money. These are nothing more than indicators to point us to the right direction. However, what this article and the previous article do demonstrate us a way to analyze the market in an attempt to find an edge.
