We all dream of knowing ahead of time entry and exit points to maximize profit from a trade. However, this seems more like a dream than reality for most of us. Tom DeMark’s “Range Expansion algorithm" tries to predict next day ranges using yesterday’s true range and Fibonacci value of 0.618 and 0.382. This exercise produces 4 values two high (H1 & H2) & 2 low (L1 and L2) [
1].
Next question is how to use this information. Here is an excerpt from “DeMark Indicator” by Jason Perl that shed some light on might use this information to enter a trade [
2].
So next question is "what is the return of such trades". Table below shows hypothetical return of trades triggered when price moved up thru H2 at H2 price and closed on next day open or high (if you know that

):-
Frankly, I am perplexed by the return for this strategy.
What do you think? I appreciate your feedback!

Here is how it is calculated.
First determine the true range (TR) of security of interest (SPY in this case) from a day earlier.
Multiply TR with 0.618 and 0.382.
Add or subtract the above from the open of next day to arrive at H1& H2 or L1& L2
Here is an example of this calculation
Previous day TR = 1.15
Today’s Open = 137.30
Then
H2 137.30 + (TR * 0.618) =138.01
H1 137.30 + (TR * 0.382) =137.74
Open 137.30 (Actual)
L1 137.30 + (TR * 0.382) =136.86
L2 137.30 + (TR * 0.618) =136.59

“…..
you can isolate instances in which, if the market breaks the first upside level, it is likely to reach the second upside level on an intraday basis.
For example, if yesterday’s close was a down close compared with the previous day’s close, and then price takes out yesterday’s true range multiplied by 0.382 and added to today’s open, there’s a good chance the up move will extend higher toward yesterday’s true range multiplied by 0.618 and added to today’s open on an intraday basis.
Conversely, if yesterday’s close was an up close compared with the previous day’s close, and then price takes out yesterday’s true range multiplied by 0.382 and added to today’s open, I’d be inclined to fade the market, and go short on an intraday basis if it reaches yesterday’s
true range multiplied by 0.618 and added to today’s open.
Similarly, if yesterday was an up close compared with the previous day’s close, and then price takes out yesterday’s true range multiplied by 0.382 subtracted from today’s open, there’s a good chance the down move will extend lower, on an intraday basis, toward yesterday’s true range multiplied by 0.618 and subtracted from today’s open.
Conversely, if yesterday’s close was a down close compared with the previous day’s close, and then price takes out yesterday’s true range multiplied by 0.382 and subtracted from today’s open, I’d be inclined to fade the market and go long on an intraday basis if price reaches yesterday’s true range multiplied by 0.618 and subtracted from today’s open.”
