我正在尝试将 thinkorswim 指标转换为交易视图松树脚本，但在绘制数据时卡住了，因为它在零处绘制直线。任何人都可以帮助绘制松树脚本的数据图
thinkorSwim 代码
input price = close;
input length = 10;
def tmp1 = if price > price[1] then price - price[1] else 0;
def tmp2 = if price[1] > price then price[1] - price else 0;
def d2 = sum(tmp1, length);
def d4 = sum(tmp2, length);
def cond = d2 + d4 == 0;
def ad3 = if cond then 0 else (d2 - d4) / (d2 + d4) * 100;
def coeff = 2 / (length + 1) * AbsValue(ad3) / 100;
def asd = compoundValue("visible data" = coeff * price + (if IsNaN(asd[1]) then 0 else asd[1]) * (1 - coeff), "historical data" = price);
plot VMA = asd;
VMA.setDefaultColor(GetColor(0));
def vwma8 = sum(volume * close, 8) / sum(volume, 8);
def vwma21 = sum(volume * close, 21) / sum(volume, 21);
def vwma34 = sum(volume * close, 34) / sum(volume, 34);
def bullish = if vwma8 > vwma21 and vwma21 > vwma34 then 1 else 0;
def bearish = if vwma8 < vwma21 and vwma21 < vwma34 then 1 else 0;
def distribution = if !bullish and !bearish then 1 else 0;
VMA.AssignValueColor(if bearish and close<= VMA then color.red else if bullish and close >= VMA then color.green else color.gray);
