Trading, You have to do that on your own as per your account size and risk taking capabilities.
Having said that, just a bit of advice. NEVER trade against the trend. at present on Hourly chart the Trend is down!!!
What i have said is to tighten the stops. This does not mean to enter Long or Buy.
As per my earlier Analysis about a week or two back, I had given my arguments for NG to come down.
This was a warning sign for those who have entered short based on that.
