안녕하세요 예스스탁입니다. 올려주신 내용은 변환이 어렵습니다. 도움을 드리지 못해 죄송합니다. 즐거운 하루되세요 > 사노소이 님이 쓴 글입니다. > 제목 : 수식 부탁드립니다 > 지표식 부탁 드립니다. //@version=5 indicator(title='Machine Learning Momentum Index (MLMI)', shorttitle='Machine Learning Momentum Index (MLMI)', overlay=false, precision=1) // ~~ ToolTips { t1 ="This parameter controls the number of neighbors to consider while making a prediction using the k-Nearest Neighbors (k-NN) algorithm. By modifying the value of k, you can change how sensitive the prediction is to local fluctuations in the data. ￦n￦nA smaller value of k will make the prediction more sensitive to local variations and can lead to a more erratic prediction line. ￦n￦nA larger value of k will consider more neighbors, thus making the prediction more stable but potentially less responsive to sudden changes." t2 ="The parameter controls the length of the trend used in computing the momentum. This length refers to the number of periods over which the momentum is calculated, affecting how quickly the indicator reacts to changes in the underlying price movements. ￦n￦nA shorter trend length (smaller momentumWindow) will make the indicator more responsive to short-term price changes, potentially generating more signals but at the risk of more false alarms. ￦n￦nA longer trend length (larger momentumWindow) will make the indicator smoother and less responsive to short-term noise, but it may lag in reacting to significant price changes." //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~} // ~~ Input Parameters { numNeighbors = input(200, title='Prediction Data (k)', tooltip=t1) momentumWindow = input.int(20, step=2, minval=10, maxval=200, title='Trend Length', tooltip=t2) //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~} // ~~ Moving Averages & RSI { MA_quick = ta.wma(close, 5) MA_slow = ta.wma(close, 20) rsi_quick = ta.wma(ta.rsi(close, 5),momentumWindow) rsi_slow = ta.wma(ta.rsi(close, 20),momentumWindow) //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~} // ~~ Crossover Conditions { pos = ta.crossover(MA_quick, MA_slow) neg = ta.crossunder(MA_quick, MA_slow) //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~} // ~~ Type Definition { type Data array<float> parameter1 array<float> parameter2 array<float> priceArray array<float> resultArray // Create a Data object var data = Data.new(array.new_float(1, 0), array.new_float(1, 0), array.new_float(1, 0), array.new_float(1, 0)) //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~} // ~~ Method that saves the last trade and temporarily holds the current one. { method storePreviousTrade(Data d, p1, p2) => d.parameter1.push(d.parameter1.get(d.parameter1.size() - 1)) d.parameter2.push(d.parameter2.get(d.parameter2.size() - 1)) d.priceArray.push(d.priceArray.get(d.priceArray.size() - 1)) d.resultArray.push(close >= d.priceArray.get(d.priceArray.size() - 1) ?
