ইক্যুইটি কার্ভ পরিচালনার উদ্দেশ্য হ'ল যখন ইক্যুইটি কার্ভ একটি ডাউনট্রেন্ডে থাকে তখন ট্রেডিংয়ে ঝুঁকি হ্রাস করা। এই কৌশলটিতে ইক্যুইটি কার্ভের ডাউনট্রেন্ড নির্ধারণের দুটি মোড রয়েছেঃ পোর্টফোলিও
যখন ট্রেডিং উইথ দ্য ইকুইটি কার্ভ" সক্রিয় থাকে, তখন পজিশনের আকার একটি নির্দিষ্ট শতাংশে হ্রাস পাবে যদি ইকুইটি একটি নির্বাচিত নিয়ম অনুসারে

If the fast SMA is below //the slow SMA, equity downtrend is detected (smafastequity < smaslowequity). //The second method is by using the crossings of equity itself with the longer-period SMA (equity < smasloweequity). //When "Reduce size by %" is active, the position size will be reduced by a specified percentage //if the equity is "under water" according to a selected rule. If you're a risk seeker, select "Increase size by %" //- for some robust systems, it could help overcome their small drawdowns quicker. //strategy("Use Trading the Equity Curve Postion Sizing", shorttitle="TEC", default_qty_type = strategy.percent_of_equity, default_qty_value = 10, initial_capital = 100000) //TRADING THE EQUITY CURVE INPUTS useTEC = input.bool(true, title="Use Trading the Equity Curve Position Sizing") defulttraderule = useTEC ? false: true initialsize = input.float(defval=10.0, title="Initial % Equity") slowequitylength = input.int(25, title="Slow SMA Period") fastequitylength = input.int(9, title="Fast SMA Period") seedequity = 100000 * .10 if strategy.equity == 0 seedequity else strategy.equity slowequityseed = strategy.equity > seedequity ? strategy.equity : seedequity fastequityseed = strategy.equity > seedequity ? strategy.equity : seedequity smaslowequity = ta.sma(slowequityseed, slowequitylength) smafastequity = ta.sma(fastequityseed, fastequitylength) equitycalc = input.bool(true, title="Use Fast/Slow Avg", tooltip="Fast Equity Avg is below Slow---otherwise if unchecked uses Slow Equity Avg below Equity") sizeadjstring = input.string("Reduce size by (%)", title="Position Size Adjustment", options=["Reduce size by (%)","Increase size by (%)"]) sizeadjint = input.int(50, title="Increase/Decrease % Equity by:") equitydowntrendavgs = smafastequity < smaslowequity slowequitylessequity = strategy.equity < smaslowequity equitymethod = equitycalc ? equitydowntrendavgs : slowequitylessequity if sizeadjstring == ("Reduce size by (%)") sizeadjdown = initialsize * (1 - (sizeadjint/100)) else sizeadjup = initialsize * (1 + (sizeadjint/100)) c = close qty = 100000 * (initialsize / 100) / c if useTEC and equitymethod if sizeadjstring == "Reduce size by (%)" qty := (strategy.equity * (initialsize / 100) * (1 - (sizeadjint/100))) / c else qty := (strategy.equity * (initialsize / 100) * (1 + (sizeadjint/100))) / c //EXAMPLE TRADING STRATEGY INPUTS CMO_Length = input.int(defval=9, minval=1, title='Chande Momentum Length') CMO_Signal = input.int(defval=10, minval=1, title='Chande Momentum Signal') chandeMO = ta.cmo(close, CMO_Length) cmosignal = ta.sma(chandeMO, CMO_Signal) SuperTrend_atrPeriod = input.int(10, "SuperTrend ATR Length") SuperTrend_Factor = input.float(3.0, "SuperTrend Factor", step = 0.01) Momentum_Length = input.int(12, "Momentum Length") price = close mom0 = ta.mom(price, Momentum_Length) mom1 = ta.mom( mom0, 1) [supertrend, direction] = ta.supertrend(SuperTrend_Factor, SuperTrend_atrPeriod) stupind = (direction < 0 ? supertrend : na) stdownind = (direction < 0? na : supertrend) //TRADING CONDITIONS longConditiondefault = ta.crossover(chandeMO, cmosignal) and (mom0 > 0 and mom1 > 0 and close > stupind) and defulttraderule if (longConditiondefault) strategy.entry("DefLong", strategy.long) shortConditiondefault = ta.crossunder(chandeMO, cmosignal) and (mom0 < 0 and mom1 < 0 and close < stdownind) and defulttraderule if (shortConditiondefault) strategy.entry("DefShort", strategy.short) longCondition = ta.crossover(chandeMO, cmosignal) and (mom0 > 0 and mom1 > 0 and close > stupind) and useTEC if (longCondition) strategy.entry("AdjLong", strategy.long) shortCondition = ta.crossunder(chandeMO, cmosignal) and (mom0 < 0 and mom1 < 0 and close < stdownind) and useTEC if (shortCondition) strategy.entry("AdjShort", strategy.short) plot(strategy.equity) plot(smaslowequity, color=color.new(color.red, 0)) plot(smafastequity, color=color.new(color.green, 0))
