Stochastic Indicator Blau_TStoch - indicatore per MetaTrader 5

Author: Andrey N. Bolkonsky

Stochastic Indicator (smoothed q-period Stochastic) by William Blau is based on Stochastic Indicator (see Momentum, Direction, and Divergence: Applying the Latest Momentum Indicators for Technical Analysis).

It shows the distance between the close price and lowest price of the q bars. The numerical value of Stochastic shows the price position relative to the lowest price of the period (q bars), the values are >=0.

Stochastic Indicator Blau_TStoch

Calculation:

The following formula is used for the calculation of q-period Stochastic:

• price - close price of the current timeframe;
• q - number of bars, used in calcualtion of Stochastic;
• LL(q) - lowest price of the q bars.

The smoothed q-period stochastic is calculated as follows:

where:

• price - close price;
• q - number of bars, used in calcualtion of Stochastic;
• stoch(price,q)=price-LL(q)- q-period Stochastic;
• EMA(stoch(price,q),r) - 1st smoothing- exponentially smoothed moving average with period r, applied to Stochastic;
• EMA(EMA(...,r),s) - 2nd smoothing - EMA of period s, applied to result of the 1st smoothing;
• EMA(EMA(EMA(...,r),s),u) - 3rd smoothing - EMA of period u, applied to result of the 2nd smoothing.

Input parameters:

• q - period, used for the calculation of Stochastic (by default q=5);
• r - period of the 1st EMA, applied to stochastic (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);
• AppliedPrice - price type (by default AppliedPrice=PRICE_CLOSE).

Note:

• q>0;
• r>0, s>0, u>0. If r, s or u =1, smoothing is not used;
• Min. rates =(q-1+r+s+u-3+1).
