Hi,

I currently use the Stochastic Momentum Index to confirm a 2nd entry point for calls on options. I'd like to be able to add it to Telechart.  It's similar to the stochastic but smoother.   Can you provide what I need to add it to Telechart?

Here's the parameters:
Days = 5
Smoothing Period = 10
Double Smoothing Period = 3
Signal EMA Period = 10
SMI is a green line
Signal = red line

Values range from +100 to -100.
Formula is found at this website:  http://www.fmlabs.com/reference/default.htm?url=SMI.htm

Here's the definition and website for an example:

http://www.prophet.net/learn/taglossary.jsp?index=S

The Stochastic Momentum Index was developed by William Blau as introduced in the in the January 1993 issue of Technical Analysis of Stocks & Commodities. While similar to the Stochastic Oscillator, the SMI displays where the close is relative to the midpoint of the recent high/low range, as compared to the close relative to the recent high/low with the Stochastic Oscillator. This results is an oscillator that ranges between -100 and +100 and can be a bit less erratic than an equal period Stochastic Oscillator.

The oscillator is comprised of two lines, the SMI (blue) and the moving average of the SMI (red). When the close is greater than the midpoint of the range, the SMI will be positive. When the close is less than the midpoint of the range, it will be negative. The interpretation of the SMI is virtually identical to that of the Stochastic Oscillator. The most basic pattern to trade from is to buy when the SMI falls below -40 and then returns above it. Sell when the SMI rises above +40 and then falls back below that level. Another trading signal is buy when the SMI rises above the moving average, and sell when the SMI falls below the moving average.

Thanks,
Craig.

I would not have known from the description given on the referenced websites that the EMA Periods could be different. Please try the following:

Select Chart Template | Add Indicator | Indicator.
- Draw Color: Green
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1)
- Indicator Formula: 200 * (9 * (XAVGC10 - (XAVG(MAXH5,10) + XAVG(MINL5,10)) / 2) - 2 * (XAVGC3 - (XAVG(MAXH5,3) + XAVG(MINL5,3)) / 2)) / (9 * (XAVG(MAXH5,10) - XAVG(MINL5,10)) - 2 * (XAVG(MAXH5,3) - XAVG(MINL5,3)))

Select Chart Template | Add Indicator | Moving Average | Formula200 * (9 * XAVGC10...
- Period: 10
- Draw Color: Red
- Average Type: Exponential
- Shift Left: Unchecked
- Visible: Checked

Bruce,

What if I need the following parameters:
Days = 8
Smoothing Period = 5
Double Smoothing Period = 5

Are my changes correct?
200 * (9 * (XAVGC5 - (XAVG(MAXH8,5) + XAVG(MINL8,5)) / 2) - 2 * (XAVGC5 - (XAVG(MAXH8,5) + XAVG(MINL8,5)) / 2)) / (9 * (XAVG(MAXH8,5) - XAVG(MINL8,5)) - 2 * (XAVG(MAXH8,5) - XAVG(MINL8,5)))

Eternum,
No. The technique used is explained in Cascades of Moving Averages but cannot be used because the Smoothing Period and Double Smoothing Period are the same (although another technique in the same topic can be used). Please try the following instead:

200 * ((XAVGC5 - (XAVG(MAXH8,5) + XAVG(MINL8,5)) / 2) + 2 / 3 * ((XAVGC5.1 - (XAVG(MAXH8.1,5) + XAVG(MINL8.1,5)) / 2) + 2 / 3 * ((XAVGC5.2 - (XAVG(MAXH8.2,5) + XAVG(MINL8.2,5)) / 2) + 2 / 3 * ((XAVGC5.3 - (XAVG(MAXH8.3,5) + XAVG(MINL8.3,5)) / 2) + 2 / 3 * ((XAVGC5.4 - (XAVG(MAXH8.4,5) + XAVG(MINL8.4,5)) / 2) + 2 / 3 * ((XAVGC5.5 - (XAVG(MAXH8.5,5) + XAVG(MINL8.5,5)) / 2) + 2 / 3 * ((XAVGC5.6 - (XAVG(MAXH8.6,5) + XAVG(MINL8.6,5)) / 2) + 2 / 3 * ((XAVGC5.7 - (XAVG(MAXH8.7,5) + XAVG(MINL8.7,5)) / 2) + 2 / 3 * ((XAVGC5.8 - (XAVG(MAXH8.8,5) + XAVG(MINL8.8,5)) / 2) + 2 / 3 * ((XAVGC5.9 - (XAVG(MAXH8.9,5) + XAVG(MINL8.9,5)) / 2) + 2 / 3 * ((XAVGC5.10 - (XAVG(MAXH8.10,5) + XAVG(MINL8.10,5)) / 2) + 2 / 3 * ((XAVGC5.11 - (XAVG(MAXH8.11,5) + XAVG(MINL8.11,5)) / 2) + 2 / 3 * ((XAVGC5.12 - (XAVG(MAXH8.12,5) + XAVG(MINL8.12,5)) / 2) + 2 / 3 * ((XAVGC5.13 - (XAVG(MAXH8.13,5) + XAVG(MINL8.13,5)) / 2) + 2 / 3 * ((XAVGC5.14 - (XAVG(MAXH8.14,5) + XAVG(MINL8.14,5)) / 2) + 2 / 3 * ((XAVGC5.15 - (XAVG(MAXH8.15,5) + XAVG(MINL8.15,5)) / 2) + 2 / 3 * ((XAVGC5.16 - (XAVG(MAXH8.16,5) + XAVG(MINL8.16,5)) / 2) + 2 / 3 * ((XAVGC5.17 - (XAVG(MAXH8.17,5) + XAVG(MINL8.17,5)) / 2))))))))))))))))))) / ((XAVG(MAXH8,5) - XAVG(MINL8,5)) + 2 / 3 * ((XAVG(MAXH8.1,5) - XAVG(MINL8.1,5)) + 2 / 3 * ((XAVG(MAXH8.2,5) - XAVG(MINL8.2,5)) + 2 / 3 * ((XAVG(MAXH8.3,5) - XAVG(MINL8.3,5)) + 2 / 3 * ((XAVG(MAXH8.4,5) - XAVG(MINL8.4,5)) + 2 / 3 * ((XAVG(MAXH8.5,5) - XAVG(MINL8.5,5)) + 2 / 3 * ((XAVG(MAXH8.6,5) - XAVG(MINL8.6,5)) + 2 / 3 * ((XAVG(MAXH8.7,5) - XAVG(MINL8.7,5)) + 2 / 3 * ((XAVG(MAXH8.8,5) - XAVG(MINL8.8,5)) + 2 / 3 * ((XAVG(MAXH8.9,5) - XAVG(MINL8.9,5)) + 2 / 3 * ((XAVG(MAXH8.10,5) - XAVG(MINL8.10,5)) + 2 / 3 * ((XAVG(MAXH8.11,5) - XAVG(MINL8.11,5)) + 2 / 3 * ((XAVG(MAXH8.12,5) - XAVG(MINL8.12,5)) + 2 / 3 * ((XAVG(MAXH8.13,5) - XAVG(MINL8.13,5)) + 2 / 3 * ((XAVG(MAXH8.14,5) - XAVG(MINL8.14,5)) + 2 / 3 * ((XAVG(MAXH8.15,5) - XAVG(MINL8.15,5)) + 2 / 3 * ((XAVG(MAXH8.16,5) - XAVG(MINL8.16,5)) + 2 / 3 * ((XAVG(MAXH8.17,5) - XAVG(MINL8.17,5))))))))))))))))))))

- Indicator Formula: 200 * (9 * (XAVGC

Select Chart Template | Add Indicator | Moving Average | Formula100 * (9 * XAVGC

One is 200 *, the other is 100 * ?

They should both be 200. The Formula200 * (9 * XAVGC is what would appear if you entered the original formula for the Custom PC Indicator.

Can you supply SMI  PCFs for

12,4,1

and

40,10,1

Thanks

If there isn't any double smoothing (the double smoothing period is 1), then the formulas are quite short and straightforward.

200 * (XAVGC4 - (XAVG(MAXH12,4) + XAVG(MINL12,4)) / 2) / (XAVG(MAXH12,4) - XAVG(MINL12,4))

And:

200 * (XAVGC10 - (XAVG(MAXH40,10) + XAVG(MINL40,10)) / 2) / (XAVG(MAXH40,10) - XAVG(MINL40,10))

Please try the following.

200 * (24 * (XAVGC25 - (XAVG(MAXH13,25) + XAVG(MINL13,25)) / 2) - (XAVGC2 - (XAVG(MAXH13,2) + XAVG(MINL13,2)) / 2)) / (24 * (XAVG(MAXH13,25) - XAVG(MINL13,25)) - (XAVG(MAXH13,2) - XAVG(MINL13,2)))

The Stochastic Momentum Index (SMI) indicator is not one of the indicators built into TC2000. You would need to create it as a Custom PCF Indicator. The exact formulas used would depend on your particular settings.
