Can you give me a formula for this below that will work on TOS?

Calculation:

1. Define current "True Low" (TL) — the least of two values: the current minimum and the precious closing price.

   TL (i) = MIN (LOW (i) || CLOSE (i - 1))




2. Find current "Buying Pressure" (BP). It is equal to the difference between current closing price and current True Low.

   BP (i) = CLOSE (i) - TL (i)




3. Define the "True Range" (TR). It is the greatest of the following differences: current maximum and minimum; current maximum and previous closing price; current minimum and previous closing price.

   TR (i) = MAX (HIGH (i) - LOW (i) || HIGH (i) - CLOSE (i - 1) || CLOSE (i - 1) - LOW (i))




4. Find the sum of BP values for all three periods of calculation:

   BPSUM (N) = SUM (BP (i), i)
   




5. Find the sum of TR values for all three periods of calculation:

   TRSUM (N) = SUM (TR (i), i)




6. Calculate the "Raw Ultimate Oscillator" (RawUO)

   RawUO = 4 * (BPSUM (1) / TRSUM (1)) + 2 * (BPSUM (2) / TRSUM (2)) + (BPSUM (3) / TRSUM (3))
   




7. Calculate the "Ultimate Oscillator" (UO) value according to the formula:

   UO = ( RawUO / (4 + 2 + 1)) * 100
   

Where:
MIN — means the minimum value;
MAX — the maximum value;
|| — a logical OR;
LOW (i) — the minimum price of the current bar;
HIGH (i) — the maximum price of the current bar;
CLOSE (i) — the closing price of the current bar;
CLOSE (i — 1) — the closing price of the previous bar;
TL (i) — the True Low;
BP (i) — the Buying Pressure;
TR (i) — the True Range;
BPSUM (N) — the mathematical sum of BP values for an n period (N equal to 1 corresponds with i=7 bars; N equal to 2 corresponds with i=14 bars; N equal to 3 corresponds with i=28 bars);
TRSUM (N) — the mathematical sum of TR values for an n period (N equal to 1 corresponds with i=7 bars; N equal to 2 corresponds with i=14 bars; N equal to 3 corresponds with i=28 bars);
RawUO — "Raw Ultimate Oscillator";
UO — stands for Ultimate Oscillator.

We don't support Think or Swim and I am not familiar with whatever language might be used with Think or Swim. My best guess at a Personal Criteria Formula to use in TC2000 for UO would be:

100 * (4 * (2 * C - L - C1 + ABS(L - C1)) / (H - L + ABS(H - C1) + ABS(C1 - L)) + 2 * (2 * AVGC2 - AVGL2 - AVGC2.1 + (ABS(L - C1) + ABS(L1 - C2)) / 2) / (AVGH2 - AVGL2 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1)) / 2) + (2 * AVGC3 - AVGL3 - AVGC3.1 + (ABS(L - C1) + ABS(L1 - C2) + ABS(L2 - C3)) / 3) / (AVGH3 - AVGL3 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2)) / 3)) / 7

Thank you very much, I actully needed for Worden charts.

You're welcome.
