Pinescript关于单次点击警报的问题。

问题描述 投票:0回答:1

战略代码

我有一个松码,根据移动平均线的状况来卖和买。该代码是这样的。

study("MAS_Alerts")

qty = input(10000, "Buy quantity")


ma1 = input( "SMA",title="Select MA", options=["SMA", "EMA","TEMA", "WMA","HMA"])


len1 = input(7, minval=1, title="Period")

s=sma(close,len1)

e=ema(close,len1)


xEMA1 = ema(close, len1)
xEMA2 = ema(xEMA1, len1)
xEMA3 = ema(xEMA2, len1)
t = 3 * xEMA1 - 3 * xEMA2 + xEMA3


f_hma(_src, _length)=>
    _return = wma((2 * wma(_src, _length / 2)) - wma(_src, _length), round(sqrt(_length)))

h = f_hma(close, len1)

w = wma(close, len1)

ma = ma1 == "SMA" ? s : ma1 == "EMA" ? e : ma1 == "WMA" ? w : ma1 == "HMA" ? h : ma1 == "TEMA" ? t : na

警戒码

现在,我试图通过添加更多的代码来使上述代码具有警报功能,你可以看到下面的代码。

long_condition = 0
long_count = 1
green = color.green
red = color.red
if(s)
    if(long_count)
        long_count := long_count - 1
        if(s < close)
            long_condition := long_condition + 1
        else
            long_condition := long_condition - 1    

plot(long_condition, "Long", color=green)   

short_condition = 0
short_count = 1

if(s)
    if(short_count)
        short_count := short_count - 1
        if(s > close)
            short_condition := short_condition + 1
        else
            short_condition := short_condition - 1    

plot(short_condition, "Short", color=red)    

我计划只在买入或卖出的条件满足时产生一次警报。

if(s)
    if(long_count)
        long_count := long_count - 1
        if(s < close)
            long_condition := long_condition + 1
        else
            long_condition := long_condition - 1    

plot(long_condition, "Long", color=green)  

或卖出

if(s)
    if(short_count)
        short_count := short_count - 1
        if(s > close)
            short_condition := short_condition + 1
        else
            short_condition := short_condition - 1    

plot(short_condition, "Short", color=red)   

只要满足一个条件,比如说,当前价格高于均线值。if(s < close) 我们就会成功地做多,因为它首先有效。在 当前的主要问题 我为什么要写这篇文章,因为价格长期停留在均线之上,根据市场走势,我的。警报代码 在条件有效的情况下,会不断发射相同的长图。我只想打印一个警报图,无论是长图还是短图,只打印一次,然后停止重复(我的意思是,如果一个长图已经被执行,我不想让它重复,直到一个新的短图条件 if(s > close) 是有效的),反之亦然,如果一个短情节已经进行了,我不希望它再次重复短情节警报,直到如果一个新的长情节条件 if(s < close) 是有效的。如何才能实现?

这使用了 barssince() 以检查消除连续进场信号。

//@version=4
study("MAS_Alerts2")

qty = input(10000, "Buy quantity")


ma1 = input( "SMA",title="Select MA", options=["SMA", "EMA","TEMA", "WMA","HMA"])


len1 = input(7, minval=1, title="Period")

s=sma(close,len1)

e=ema(close,len1)


xEMA1 = ema(close, len1)
xEMA2 = ema(xEMA1, len1)
xEMA3 = ema(xEMA2, len1)
t = 3 * xEMA1 - 3 * xEMA2 + xEMA3


f_hma(_src, _length)=>
    _return = wma((2 * wma(_src, _length / 2)) - wma(_src, _length), round(sqrt(_length)))

h = f_hma(close, len1)

w = wma(close, len1)

ma = ma1 == "SMA" ? s : ma1 == "EMA" ? e : ma1 == "WMA" ? w : ma1 == "HMA" ? h : ma1 == "TEMA" ? t : na
long_condition = 0
long_count = 1
green = color.green
red = color.red

long_trigger = s < close
short_trigger = s > close
b_since_long = barssince(long_trigger)[1]
b_since_short = barssince(short_trigger)[1]
if(s)
    if(long_count)
        long_count := long_count - 1
        if long_trigger and b_since_long > b_since_short
            long_condition := long_condition + 1
        else
            long_condition := long_condition - 1    

plot(long_condition, "Long", color=green)   

short_condition = 0
short_count = 1

if(s)
    if(short_count)
        short_count := short_count - 1
        if short_trigger and b_since_short > b_since_long
            short_condition := short_condition + 1
        else
            short_condition := short_condition - 1    

plot(short_condition, "Short", color=red)    
bgcolor(long_trigger ? color.green : short_trigger ? color.red : na)
plotchar(b_since_long, "b_since_long", "", location.top, size = size.tiny)
plotchar(b_since_short, "b_since_short", "", location.top, size = size.tiny)

上面是你的,下面是新版本enter image description here
