Inside technicals and chart patterns by 
When economic releases approach it’s important to consider the volatility that could accompany the data. Tonight’s 7:00pm EST CB Leading Index release will likely dictate which of the swing entries I will consider. If prices are very close to the triggering the swing short on teh 15 minute chart (top) then there is more risk as prices could be more volatile right near the entry price and stop my trend follow out as prices settle down. However if prices shoot lower from the 0.8993 area the 30 minute chart (bottom) may not trigger at all. So here’s the question you must ask yourself:
Since you don’t know the future the main issue is your own risk tolerance. If prices are near the 15 minute trigger you could wait for the more conservative swing short IF you have a low risk tolerance. If your risk tolerance is HIGH then take the 15 minute entry…it’s the bird in the hand.
