BarroMetrics Views: Overcoming Bias
I was asked to give an example of overcoming bias, especially confirmation bias. I’m happy to oblige.
Let’s look at the GBPUSD.
You’ll recall that some readers (and I) made good money anticipating Brexit (see BarroMetrics Views: Brexit, A Trade Post Morterm).
After the ‘flash crash’ (red arrow, Figure 2), I decided to take the pair off my radar until the effects of the crash had dissipated. I felt that the move had not only taken out all the stops that would have provided some directional move (around the 1.3000 level), it also meant that the GBPUSD would need time to digest the volatility.
That was over five months ago, time enough for the effects to be forgotten. So recently, I placed the pair back on my watch list. When I do that, the first thing I do is the answers to two questions:
The answers provide me with my strategy (go long or short or stand aside). And, my first step to clarify the strategy is to review my long-term and 12-month swing charts.
Figure 1 is a long-term monthly chart going back to 1900. I suspect it is a spot monthly of the futures market because the prices and dates of swing highs and swing lows don’t quite match up with the FX data. Nevertheless, the chart is useful for perspective.
Notice from the chart:

The two charts provide the background, the context, to my trader’s timeframe (18-day swing line representing the monthly trend).
My conclusions are that the trend will probably be down, and likely to continue: a downtrend established by a break below a 25-year old pattern does not reverse in 12-months.
My conclusions also form my bias.
More tomorrow.
