The US session alone accounts for round 20% and within the US Afternoon, you’ll typically see a pointy drop off in aggressive strikes apart from when the Federal Open Market Committee (FOMC) comes out with a shock announcement which is however a number of instances a yr.

Liquidity Risk vs Reward

The relationship between threat and reward in monetary markets is nearly at all times proportionate, so understanding the dangers concerned in a commerce have to be considered.

A main instance of liquidity threat within the foreign exchange market is the Swiss Franc disaster in 2015. The Swiss central financial institution introduced they’d now not be preserving the Swiss Franc peg towards the Euro inflicting the interbank market to grow to be damaged as a consequence of an incapability to cost the market. This led to brokers being unable to supply liquidity on CHF. As interbank pricing (the spine of foreign exchange pricing) returned, EUR/CHF costs have been removed from the earlier vary.
