1. About Correlation
The Correlation Trader shows the correlation between symbols over a configurable
recent H1 bars.
Correlation is measured on a scale from -100 to +100:
- +100 means that the price movements in symbol A and B have been identical (“positive correlation”).
- -100 means that the price movements in symbol A and B have been exactly opposite: A went up when B
went down, and vice versa (“negative correlation”).
- 0 means that the symbols have moved independently.
Correlation can have a major effect on your trading risk. For example the following charts show H1 EURUSD
and USDCHF over the same time period:
These symbols had very strong negative correlation (about -95). If you were long EURUSD and short
USDCHF over this period, or vice versa, then you would have seen very similar profits on both positions.
In effect, you did not have two positions: you only really had one position. (If you were long both
symbols, or short both symbols, then you probably had a profit on one and a matching loss on the
It is generally advisable to minimise the correlation between your open positions.
Otherwise, you are either trading the same price action twice over, or you have two positions which
cancel each other out.
The Correlation Trader helps you to identify symbols with strong or weak
correlation, and to trade emerging differences in the correlation.
2. Using the Correlation Trader
2.1 Price charts
The Correlation Trader shows recent price charts for two symbols side by side (and can be used simply as
a way of displaying two linked price charts):
The bar in the middle lets you change the timeframe for the charts.
It also shows the following:
- Recent correlation between the two symbols over the selected timeframe.
- Any open position in each symbol, and its profitability
2.2.1 Correlation values
The gauge shows the correlation on scale of 0 to ± 100.
It makes little difference whether values are positive or negative (e.g. +90 or -90), and the meaning
depends on whether you are long or short each symbol. For example:
- +90. If you are long both symbols, or short both symbols, then you will tend to seeidentical profits
or losses on both positions. If you are long one symbol and short the other, then you will tend to
have a matching profit and loss.
- -90. If you are long both symbols, or short both symbols, then you will tend to have a matching
profit and loss. If you are long one symbol and short the other, then you will tend to see identical
profits or losses on both positions.
