One of my favorite leading indicators is the Average True Range (ATR). There is technically two different thoughts on ATR, but I like to use the leading version instead of the lagging.
ATR gives you an idea of the typical move a stock may move in a day
If price has risen $2 already and has a $5 true range, there may be room for it to grow
This is not absolute, and a stock does not always move by the ATR, but if a stock is up $10 on a $5 ATR, I would be cautious about entering, looking to take profits, or looking for reversals. At this point is pushing its upper limits and may do one of three things:
Hold, contract, or push ahead
For conservatives, avoid entering in the same direction of the movement if it has moved greater than or equal to its ATR
Consider playing a reversal if price action calls for it
Consider holding if you are a long term holder or swinging through for a longer term; intraday does not matter to swing traders looking at weeks to months
Catalysts can throw ATR out the window and you could see exponential moves that hold throughout the day
Some will use an ATR Indicator, but I have not seen any useful practices of the ATR. Check them out on YouTube and decide if it fits your trading style.
