Ergodic CSI-Oscillator by William Blau

Calculation:

The CSI Oscillator is defined as follows:

where:

• Ergodic_CSI() – Erogic line – Candlestick Index CSI(price1,price2,q,r,s,u);
• SignalLine() – Signal Line – EMA(ul), applied to Ergodic;
• ul – period of a Signal Line.

Input parameters:

• graphic plot #0 – Ergodic Line (Candlestick Index):
• q – number of bars, used in calculation of Candlestick Momentum (by default q=1);
• r – period of the 1st EMA, applied to Candlestick Momentum (by default r=20);
• s – period of the 2nd EMA, applied to result of the 1st smoothing (by default s=5);
• u – period of the 3rd EMA, applied to result of the 2nd smoothing (by default u=3);
• graphic plot #1 – Signal Line:
• ul – period of a Signal Line, EMA(ul) is applied to Ergodic (by default ul=3);
• AppliedPrice1 – price type (by default AppliedPrice1=PRICE_CLOSE);
• AppliedPrice2 – price type (by default AppliedPrice2=PRICE_OPEN).

Note:

• q>0;
• r>0, s>0, u>0. If r, s or u are equal to 1, the smoothing is not used;
• ul>0. If ul=1, the Signal and Ergodic Lines are the same;
• Min. rates = (q-1+r+s+u+ul-4+1).
