This alternative data in action post looks at the power of currency volume data. CLS has just published the first true global foreign exchange FX volume database. Commercially available for the first time via Quandl, this database is the most accurate, most comprehensive and timeliest gauge of currency trading volume ever published.
This is the first time we have been able trading strategie bollinger bnder incorporate volume data into an FX trading strategy. The price of a financial asset is, precisely, what market participants are willing to pay for it. The best systematic trading strategies in global equity markets today leverage volume information almost as trading strategie bollinger bnder as price data, to the point that an algorithm would be crippled were volume data withheld. However, the same cannot be said of the FX market: Compared to their peers in equity, FX traders fly blind.
Trends are trivial to spot in hindsight. The trading strategie bollinger bnder and science of trend following aka momentum investing requires an investor to detect a trend in its nascence.
How exactly to do this is the stuff of passionate debate and indeed what separates the best investors in the world from the rest of us. For the purpose of testing the marginal impact of volume data on FX trend following we chose the classic Bollinger band breakout strategy.
This approach is too simple to truly deliver good results in practice, but our purpose is to explore the marginal impact of volume information on systematic FX trading. So we just needed a baseline. Bollinger Band breakout is a well-documented trend following strategy.
The basic idea is that a trend begins if the price of an asset moves outside its recent price range. For trading strategie bollinger bnder, one might define the breakout threshold to be twice the day volatility of the asset:. An investor buys or short sells the asset when a breakout occurs and holds the position as long as the price remains above below the simple moving average SMA of its price.
We tested the strategy over the past 5 trading strategie bollinger bnder. Our somewhat arbitrary parameters were:. Note the performance is poor. It is in fact better with different parameterizations, but we felt it prudent to use canonical parameter choices.
What we really want to find out is what happens if we augment this strategy with volume data. Volume promises to be helpful in a trend following strategy because the fundamental challenge of trading strategie bollinger bnder strategy is avoiding false starts.
Incorrectly trading strategie bollinger bnder that a trend has begun will, at best, create unrewarded volatility and at worst lose money. We can now finally use volume information to increase conviction around trends with the CLS Daily database.
We can augment our trading rule to require not only a price breakout but also a meaningful increase in volume at the same time. Notice trading strategie bollinger bnder is the same trend follow strategy as above, with an additional volume threshold that must be met before taking a position.
We reran the backtest for various values of these three parameters. For N we tried 22, 32 and For M we tried 1, 2, 1. Some of these 81 permutations are big winners and others are big losers in terms of returns and risk-adjusted returns. In 77 of 81 permutations, the volume-augmented variation of the strategy delivers higher risk adjusted returns in Sharpe ratio terms than the pure price strategy!
