Zigzaglibrary

ZigLibLibrary "ZigLib" Calculate the points for ZigZag++. You can use custom data and resolution for your ZigZag++. Sample Usage import DevLucem/ZigLib/1 as ZigZag = ZigZag.zigzag(low, high) bgcolor(direction<0? color.rgb(255, 82, 82, 80): color.rgb(0, 230, 119, 80)) line zz = line.new(z1.time, z1.price, z2.time, z2.price, xloc.bar_time, width=3) if direction==direction line.delete(zz ) zigzag(_low, _high, depth, deviation, backstep) Get current zigzag points and direction   Parameters:      _low (float)      _high (float)      depth (int)      deviation (int)      backstep (int) Returns direction, chart point 1 and chart point 2

zigzagplusThis is same as existing zigzag library with respect to functionality. But, there is a small update with respect to how arrays are used internally. This also leads to issues with backward compatibility. Hence I decided to make this as new library instead of updating the older one. Below are the major changes: Earlier version uses array.unshift for adding new elements and array.pop for removing old elements. But, since array.unshift is considerably slower than alternative method array.push. Hence, this library makes use of array.push method to achieve performance. While array.push increases the performance significantly, there is also an issue with removing as we no longer will be able to remove the element using pop which is again faster than shift (which need to shit all the elements by index). Hence, have removed the logic of removing elements for zigzag pivots after certain limit. Will think further about it once I find better alternative of handling it. These implementation change also mean that zigzag pivots received by calling method will be ordered in reverse direction. Latest pivots will be stored with higher array index whereas older pivots are stored with lower array index. This is also the reason why backward compatibility is not achievable with this code change. Library "zigzagplus" Library dedicated to zigzags and related indicators zigzag(length, useAlternativeSource, source, oscillatorSource, directionBias) zigzag: Calculates zigzag pivots and generates an array   Parameters:      length : : Zigzag Length      useAlternativeSource : : If set uses the source for genrating zigzag. Default is false      source : : Alternative source used only if useAlternativeSource is set to true. Default is close      oscillatorSource : : Oscillator source for calculating divergence      directionBias : : Direction bias for calculating divergence   Returns: zigzagpivots : Array containing zigzag pivots zigzagpivotbars : Array containing zigzag pivot bars zigzagpivotdirs : Array containing zigzag pivot directions (Lower High : 1, Higher High : 2, Lower Low : -2 and Higher Low : -1) zigzagpivotratios : Array containing zigzag retracement ratios for each pivot zigzagoscillators : Array of oscillator values at pivots. Will have valid values only if valid oscillatorSource is provided as per input. zigzagoscillatordirs: Array of oscillator directions (HH, HL, LH, LL) at pivots. Will have valid values only if valid oscillatorSource is provided as per input. zigzagtrendbias : Array of trend bias at pivots. Will have valid value only if directionBias series is sent in input parameters zigzagdivergence : Array of divergence sentiment at each pivot. Will have valid values only if oscillatorSource and directionBias inputs are provided newPivot : Returns true if new pivot created doublePivot : Returns true if two new pivots are created on same bar (Happens in case of candles with long wicks and shorter zigzag lengths) drawzigzag(length, , source, linecolor, linewidth, linestyle, oscillatorSource, directionBias, showHighLow, showRatios, showDivergence) drawzigzag: Calculates and draws zigzag pivots   Parameters:      length : : Zigzag Length      : useAlternativeSource: If set uses the source for genrating zigzag. Default is false      source : : Alternative source used only if useAlternativeSource is set to true. Default is close      linecolor : : zigzag line color      linewidth : : zigzag line width      linestyle : : zigzag line style      oscillatorSource : : Oscillator source for calculating divergence      directionBias : : Direction bias for calculating divergence      showHighLow : : show highlow label      showRatios : : show retracement ratios      showDivergence : : Show divergence on label (Only works if divergence data is available - that is if we pass valid oscillatorSource and directionBias input)   Returns: zigzagpivots : Array containing zigzag pivots zigzagpivotbars : Array containing zigzag pivot bars zigzagpivotdirs : Array containing zigzag pivot directions (Lower High : 1, Higher High : 2, Lower Low : -2 and Higher Low : -1) zigzagpivotratios : Array containing zigzag retracement ratios for each pivot zigzagoscillators : Array of oscillator values at pivots. Will have valid values only if valid oscillatorSource is provided as per input. zigzagoscillatordirs: Array of oscillator directions (HH, HL, LH, LL) at pivots. Will have valid values only if valid oscillatorSource is provided as per input. zigzagtrendbias : Array of trend bias at pivots. Will have valid value only if directionBias series is sent in input parameters zigzagdivergence : Array of divergence sentiment at each pivot. Will have valid values only if oscillatorSource and directionBias inputs are provided zigzaglines : Returns array of zigzag lines zigzaglabels : Returns array of zigzag labels
