The Market Overview is a perfect tool to find the market correlations.
On the picture below you can see that Indonesia is in a 13 day downtrend (7% drop). If you want to learn about the world markets you can spot that Thailand has also dropped 5.99% in the same period of time.
This leaves a conclusion that those markets (at least lately) have been correlated.
You can use such knowledge in the future. Let’s say you will spot that Indonesia is reversing its move, then you can then start monitoring Thailand and take long positions there.
You can do the same on other pairs of instruments of course – just find correlations, the Market Overview is a perfect tool to do it.
