Euro is heading higher in forex trading right now, recapturing some of the gains it lost earlier. It's been a choppy day for the currency market. Earlier, the euro saw gains as optimism over Greece took hold. Then, those gains were pared as the optimism faded. Now, though, there is enough hope again to help the euro.

It's been an interesting day as forex traders and others wait to see what kind of help the European Central Bank will offer Greece, and what measures Greek leaders will accept.

For now, euro is higher in forex trading. It has edge out the US dollar and is looking for some gains. However, a slight change in sentiment, or the smallest hint of bad news, could overset the gains and send the euro lower against the US dollar again. 

US dollar is gaining in currency trading right now, thanks to worries about what's next for the eurozone. Confidence in the euro is being shaken a bit by the fact that Greek debt talks have been put off -- again.

Risk aversion is high, and that means that many forex traders are looking for safe haven. The US dollar has been serving as a safe haven, since it is backed by what many consider to be the most stable taxpayer base in the world.

High beta currencies are pulling back against the US dollar for now, with the euro, pound and loonie all lower. High beta currencies are not in demand right now as forex traders look for safety, rather than yields.

Positive manufacturing data out of the UK is helping the pound today in forex trading. The news about manufacturing was better than expected, and this is helping the sterling against the US dollar in currency trading.

Indeed, the news has some hoping that Britain's economy is ready to show signs of recovery. Britain has been in a tough place lately, with slow economic expansion, but inflation higher than the Bank of England has been comfortable with.

There are hopes now for the British economy, and that is being reflected by the pound's improvement in forex trading. Also boosting the pound is the fact that stock markets are higher today. Equities around the world are gaining ground on general risk appetite, and that is helping high beta currencies like the pound in their performances against the US dollar.
