This indicator combines the volatility and momentum components of Bollinger Bands and Keltner Channels to help traders predict when a price might break out of. The most common choices are a 14 period %K and a 3 period SMA for %D. The second line (%D) is a Simple Moving Average of the %K line. The first line (%K) displays the current close in relation to the period's high/low range. It is a range-bound oscillator with two lines moving between 0 and 100. He believed this indicator was a good way to measure momentum because changes in momentum precede changes in price. """Stochastic (STOCH) The Stochastic Oscillator (STOCH) was developed by George Lane in the 1950's. fillna ( method = kwargs, inplace = True ) # Name and Categorize it _name = "STOCH" _props = f "_ " df. ![]() fillna ( method = kwargs, inplace = True ) stoch_d. fillna ( kwargs, inplace = True ) if "fill_method" in kwargs : stoch_k. fillna ( kwargs, inplace = True ) stoch_d. shift ( offset ) # Handle fills if "fillna" in kwargs : stoch_k. loc, length = d ) # Offset if offset != 0 : stoch_k = stoch_k. loc, length = smooth_k ) stoch_d = ma ( mamode, stoch_k. max () stoch = 100 * ( close - lowest_low ) stoch /= non_zero_range ( highest_high, lowest_low ) stoch_k = ma ( mamode, stoch. ![]() I check different indicators under the triple screen framework, and the Squeeze Momentum Indicator is in the intermediate screen.Def stoch ( high, low, close, k = None, d = None, smooth_k = None, mamode = None, offset = None, ** kwargs ): """Indicator: Stochastic Oscillator (STOCH)""" # Validate arguments k = k if k and k > 0 else 14 d = d if d and d > 0 else 3 smooth_k = smooth_k if smooth_k and smooth_k > 0 else 3 _length = max ( k, d, smooth_k ) high = verify_series ( high, _length ) low = verify_series ( low, _length ) close = verify_series ( close, _length ) offset = get_offset ( offset ) mamode = mamode if isinstance ( mamode, str ) else "sma" if high is None or low is None or close is None : return # Calculate Result lowest_low = low. Also, Mr.Carter uses simple momentum indicator, while I have used a different method (linreg based) to plot the histogram. My (limited) experience with this shows, an additional indicator like ADX / WaveTrend, is needed to not miss good entry points. Exit the position when the momentum changes (increase or decrease - signified by a color change). Mr.Carter suggests waiting till the first gray after a black cross, and taking a position in the direction of the momentum (for ex., if momentum value is above zero, go long). This signifies low volatility , market preparing itself for an explosive move (up or down). This is a derivative of John Carter’s “TTM Squeeze” volatility indicator, as discussed in his book “Mastering the Trade” (chapter 11).īlack crosses on the midline show that the market just entered a squeeze ( Bollinger Bands are with in Keltner Channel). ![]()
