需要在tradingview - pinescript中删除前一天的绘图

Question

这是我的代码。你能不能更新一下你的答案，因为我试过了，指标没有正确编译。

//@version = 3

研究(title ="TEST"覆盖= true)

fib1 = security(tickerid，"D"，high[1]， lookahead=barmerge.lookahead_on)

fi0 = security(tickerid，"D"，low[1]， lookahead=barmerge.lookahead_on)

plotS1 = input(title="Plot S1"， type=bool, defval=true)

plotR1 = input(title="Plot R1"， type=bool, defval=true)

R1 = (fib -fib1)*0.215+fib1

S1 = (fib -fib1)*0.79+fib1

情节(系列= plotR1吗?R1: na, title="R1"， style=cross, linewidth=1, color=#EEC900) plot(series=plotS1 ?[font =宋体，font =宋体，font =宋体，font =宋体，font =宋体，font =宋体]

Answer 1

//@version=4
study("Fib", "FiB", true)
[fib1,fib0] = security(syminfo.tickerid, "D", [high[2], low[2]], lookahead=barmerge.lookahead_on)
is_today = year == year(timenow) and month == month(timenow) and dayofmonth == dayofmonth(timenow)
plot(fib0, "fib0", is_today ? color.green : na)
plot(fib1, "fib1", is_today ? color.blue  : na)
