Personally, I trade both but use position size management. For example, during trends...I play the position size game even in pullbacks of the trend. Thus, if its a downtrend...I'm normal to heavy on the Shorts but light on the Longs...the Longs aren't really looking for reversals. In contrast, the Longs are just trying to exploit a few points of counter-thrust back upwards before the price action rolls over southward again and these types of Longs tend to have smaller profit targets. As to reversals, I don't like to trade them with the thought its reversing and will turn into an Uptrend but I do sometimes via a smaller position size to manage the increased risk of trading reversals and with the goal of a bigger profit target than a typical Long I mentioned earlier.
