Question

我正在努力在tradingview中创建趋势指标，以跟踪趋势的发展方向。具体来说，我希望变量在几天内保持不变，但是当满足特定条件时它将改变。看起来这应该很简单，但是每次尝试时，我都会陷入一个永无止境的循环中，而且似乎无法将自己的头缠住。变量“趋势”


///Condition
pos = close > open
neg = close < open

pos_cond = pos and pos[1]
neg_cond = neg and neg[1]

///Variables to keep track of trend

Trend = iff(***pos_cond or neg_cond not met***, Trend[1], Trend + real_trend)

trend_change_neg = iff(pos_cond, 1, 0)
trend_change_pos = iff(neg_cond, -1, 0)

real_trend = trend_change_neg + trend_change_pos

Trend = iff(Trend > 2, 2, iff(Trend < -2, -2, Trend))

/////////plots
plotshape(Trend > 0, color = color.green, location = location.top, style = shape.square, title="TrendLong")

plotshape( Trend == 0, color = color.yellow, location = location.top, style = shape.square, title = "TrendNeutral")

plotshape( Trend < 0, color = color.red, location = location.top, style = shape.square, title = "TrendShort")

所以基本上我想要做的是保持趋势的运行总计，每次有2个连续的蜡烛与趋势相对时，它将切换到中性，但是随着趋势继续向1个方向移动，它可以恢复到+ -2（这是我们与中立点之间的距离不超过2个“回撤”。我已经花了好几天时间思考这个问题，但是如果有人有任何想法，将不胜感激。

您需要使用var。示例：

var a = 0
a:=close>open?1:0
