Tradingview Pine 脚本在策略进入时保存收盘价 [英] Tradingview Pine script save close price at time of strategy entry

问题描述

嘿，我正在尝试将 strategy.entry 时的收盘价保存到一个变量中，以便我以后可以使用它来退出.

Hey I'm trying to save the close price at the time of strategy.entry to a variable so I can use it later for an exit.

if condition
    strategy.entry("long", true)
    buyprice=close
(strategy.exit("exit","long", when = close>buyprice*1.1) 

我收到错误:未声明的标识符buyprice".据我了解，这意味着该变量在 if 语句之外无效.有没有办法改变这种情况?预先感谢您的帮助

I get the error: Undeclared identifier 'buyprice'. From what I understand this means that the variable is not valid outside of the if statement. Is there a way to change this? Thanks in advance for your help

推荐答案

这是 是我让它发挥作用的唯一方法.

This is the only way that I could get this to work.

基本上，您在满足多头条件时设置之前的价格，然后在下一阶段从全局变量中检索该值.

Basically, you set the previous price when long condition is met and then retrieve that value from the global variables in the next phase.

//@version=2
...
buyprice=buyprice[1]


golong=...

if golong
    buyprice := close

goshort=... or close<=buyprice*0.95

strategy.entry("Long", long=true, when=golong)
strategy.close("Long", when=goshort)
