My recent bonus post explained one of the ways that I've found helpful to think about and calculate price targets for the trading day. As background for this topic, please check out the posts on defining effective price targets and the importance of volatility in trade planning.
This will be my second and final bonus post on the topic. As with the earlier one, I will be keeping it on the site for a limited time as a thanks to current readers. If the ideas interest you, you might want to print the post out or jot down the relevant ideas.
In this post, I will explain how I calculate the daily price targets that I post each morning via Twitter. I'm in the process of tweaking my weekly target calculations and will wait for a future occasion to share those.
The calculations begin with the day's pivot level, as I define it:
Pivot = (H + L +2C)/4
Today's pivot price is defined as the average of yesterday's high price plus yesterday's low price plus two times yesterday's closing price. That gives us an approximation of yesterday's average trading price.
Going back to late 2002, we touch the pivot level during today's trade on 70% of all trading days. This is a useful "reversion" target if we open above the pivot, but cannot sustain buying or if we open below pivot and cannot sustain selling. (The current day's VWAP for the index futures contracts is generally my first reversion target).
As mentioned in the earlier post, the overnight high and low price and the prior day's high and low are generally my first price targets. Along with the pivot level and VWAP, those are generally targets for the first trades I will place during the day. Once I know those targets, it's a matter of: 1) discerning the balance between buying and selling sentiment, as well as sector and intermarket dynamics, to gauge direction; 2) assessing today's volume relative to yesterday's (and the prior five days' average volume) to gauge evolving volatility; 3) executing the trade in the identified direction at a price that provides a favorable level of reward relative to risk; and 4) holding the trade to the price target most likely to be hit given the market's current strength and volatility.
(The above paragraph is a concise description of how I trade on the day time frame).
The price targets above the prior day's high are identified as R1, R2, and R3. The price targets below the prior day's low are identified as S1, S2, and S3.
To calculate this levels, we need an estimate of recent volatility. That estimate in my calculations is the median daily price range for the past five trading sessions in SPY. Thus, each day we calculate the Daily Range: DR=((H-L)/O)*100. That is the difference between the day's high and low prices divided by the opening price multiplied times 100 (to give us a percentage). The Volatility estimate (V) for our calculations is the median of the prior five days' DR values.
As I mentioned earlier, going back to 2002, the median volatility for the prior five days correlates with today's volatility by .80. Knowing V gives us a good idea for today's DR.
So now we can define our R and S price targets:
R1 = Pivot + (.60*V)
S1 = Pivot - (.60*V)
Going back to 2002, we touch R1 or S1 about 84% of the time. If the volume today is anything like yesterday's volume, R1 or S1 should be hit during the day.
R2 = Pivot + (.80*V)
S2 = Pivot - (.80*V)
Going back to 2002, we touch R2 or S2 about 66% of the time. If today's volume is above average, we should hit R2 or S2 during the day.
R3 = Pivot + V
S3 = Pivot - V
Going back to 2002, we touch R3 or S3 about 50% of the time. If today's volume is meaningfully above average, we should hit R3 or S3 during the day.
R4 = Pivot + 1.2 V
S4 = Pivot - 1.2 V
Going back to 2002, we touch R4 or S4 about 36% of the time. We need to see volume today much greater than the recent average volume to have confidence in hitting R4 or S4.
Obviously, you could define R5 and S5 levels (and beyond) accordingly for relatively rare occasions of high volume trending and range breakouts.
NOTES ON THE CALCULATIONS
These price levels were calculated and tested empirically in Excel using historical data. They are not based on any Fib or any other numerical scheme.
A worthwhile tweak on the above methodology would be to use today's Open price in lieu of the Pivot for the calculations.
Another tweak substitutes weekly data for daily data to use for swing trading.
Another tweak is to adapt the formulas to different trading markets.
Knowing how far a market is likely to move in a direction is invaluable in guiding the placement of stop and exit levels and calculating the risk/reward parameters of a trade. By adjusting price targets for recent volatility, traders can adapt quickly to faster and slower market conditions. The price targets are not necessarily hard exit levels; rather, they provide anticipation of where those proper exits are likely to occur.
