Yes I've done what Earl is speaking of. I use a 2 day ROC pivot point to
trade short term swings in the market. I took the basic ROC equation and
solved for the next day. Here's the EL code I used to do it
Where: RateOfChange = (Price/Price[Length] - 1) * 100 converts to this to
find next day's price:
EPrice is sent today's close when it is called:
Function Name: TS_STPivot
Inputs: ePric(NumericSeries);
Var : iRawPrice(0);
iRawPrice = 0;
iRawPrice = c[1] * RateOfChange(ePrice,2)[0] / 100);
TS_STPivot = iRawPrice
For more complex formulas that aren't easily solved for the next day's
price, I take an iterative approach and keep plugging in prices until the
OSC is flipped for the first time. Here's an outline of process I used:
1. If the OSC is going down (this day < previous day) then start with a
price that is less than the current one to keep the OSC going down. Ex: 25%
of closing price (purely arbitrary but ensure that the first value will
always keep the OSC going in the same direction)
2. Verify that this price value will infact keep the OSC going the same
direction if tomorrow were to close here.
3. Then start working up/down plugging in succesively lower/higher values in
units of 0.001 until you get the same value that currently exists in the OSC
today.
4. Any price above (if OSC line going down) /below (if OSC line going up)
this value should flip the OSC.
Hope this helps.
Brian.

It's generally relatively simple algebra to turn any indicator formula
around to solve for the unknown value to yield a known result instead of the
usual known value to yield unknown result.
