pine-script - 将 pinescript v2 转换为 v3 时遇到问题
问题描述
我想在 Pinescript 中将这段代码从 v2 转换为 version3 或 4。我尝试遵循一些教程,但我没有找到任何信息如何处理版本之间的转换
//@version=3
strategy(title = "Strategy_upgrade_try", shorttitle = "Symphony 1.1", overlay = false, default_qty_type = strategy.percent_of_equity, default_qty_value = 100, pyramiding = 20)
//Settings
//needlong = input(true, defval = true, title = "Long")
//needshort = input(true, defval = true, title = "Short")
capital = input(100, defval = 100, minval = 1, maxval = 10000, title = "Lot, %")
usersi1 = input(true, defval = true, title = "Use RSI 1")
rsiperiod1 = input(4, defval = 4, minval = 2, maxval = 100, title = "RSI 1 Period")
rsilimit1 = input(20, defval = 20, minval = 2, maxval = 50, title = "RSI 1 Limit")
usersi2 = input(true, defval = true, title = "Use RSI 2")
rsiperiod2 = input(7, defval = 7, minval = 2, maxval = 100, title = "RSI 2 Period")
rsilimit2 = input(25, defval = 25, minval = 2, maxval = 50, title = "RSI 2 Limit")
usersi3 = input(true, defval = true, title = "Use RSI 3")
rsiperiod3 = input(14, defval = 14, minval = 2, maxval = 100, title = "RSI 3 Period")
rsilimit3 = input(30, defval = 30, minval = 2, maxval = 50, title = "RSI 3 Limit")
usersi4 = input(false, defval = false, title = "Use RSI 4")
rsiperiod4 = input(21, defval = 21, minval = 2, maxval = 100, title = "RSI 4 Period")
rsilimit4 = input(35, defval = 35, minval = 2, maxval = 50, title = "RSI 4 Limit")
usersi5 = input(false, defval = false, title = "Use RSI 5")
rsiperiod5 = input(28, defval = 28, minval = 2, maxval = 100, title = "RSI 5 Period")
rsilimit5 = input(40, defval = 40, minval = 2, maxval = 50, title = "RSI 5 Limit")
cf = input(false, defval = false, title = "Use color filter")
fromyear = input(1900, defval = 1900, minval = 1900, maxval = 2100, title = "From Year")
toyear = input(2100, defval = 2100, minval = 1900, maxval = 2100, title = "To Year")
frommonth = input(01, defval = 01, minval = 01, maxval = 12, title = "From Month")
tomonth = input(12, defval = 12, minval = 01, maxval = 12, title = "To Month")
fromday = input(01, defval = 01, minval = 01, maxval = 31, title = "From Day")
today = input(31, defval = 31, minval = 01, maxval = 31, title = "To Day")
//RSI
rsi1 = rsi(close, rsiperiod1)
rsi2 = rsi(close, rsiperiod2)
rsi3 = rsi(close, rsiperiod3)
rsi4 = rsi(close, rsiperiod4)
rsi5 = rsi(close, rsiperiod5)
//Signals
up1 = rsi1 < rsilimit1 and usersi1
up2 = rsi2 < rsilimit2 and usersi2
up3 = rsi3 < rsilimit3 and usersi3
up4 = rsi4 < rsilimit4 and usersi4
up5 = rsi5 < rsilimit5 and usersi5
str = up5 ? 5 : up4 ? 4 : up3 ? 3 : up2 ? 2 : up1 ? 1 : str[1]
up = up1 or up2 or up3 or up4 or up5
exit = (rsi1 > rsilimit1 and str == 1) or (rsi2 > rsilimit2 and str == 2) or (rsi3 > rsilimit3 and str == 3) or (rsi4 > rsilimit4 and str == 4) or (rsi5 > rsilimit5 and str == 5)
lot = strategy.position_size == 0 ? strategy.equity / close * capital / 100 : lot[1]
//Background
col = up ? lime : na
bgcolor(col, transp = 0)
//Trading
if up and (close < open or cf == false)
strategy.entry("Long", strategy.long, lot, when=(time > timestamp(fromyear, frommonth, fromday, 00, 00) and time < timestamp(toyear, tomonth, today, 23, 59)))
if time > timestamp(toyear, tomonth, today, 23, 59) or exit
strategy.close_all()
在控制台中我得到:
Processing script...
line 48: Undeclared identifier `str`;
line 50: Undeclared identifier `str`;
line 51: Undeclared identifier `lot`;
我对此完全陌生,我将不胜感激。
解决方案
我已将其转换为版本 4。
问题是您试图使用历史值[1]
,str
但该值lot
尚不存在。所以你必须先定义它们,像这样:
var int str = na
var float lot = na
然后你需要为它们分配一个值,:=
而不是=
另外,我已经删除了defval
你的input
函数部分,因为第一个参数已经是defval
. 无需定义defval
两次,因为编译器将其视为错误。
这将起作用:
//@version=4
strategy(title = "Strategy_upgrade_try", shorttitle = "Symphony 1.1", overlay = false, default_qty_type = strategy.percent_of_equity, default_qty_value = 100, pyramiding = 20)
//Settings
//needlong = input(true, defval = true, title = "Long")
//needshort = input(true, defval = true, title = "Short")
capital = input(100, minval = 1, maxval = 10000, title = "Lot, %")
usersi1 = input(true, title = "Use RSI 1")
rsiperiod1 = input(4, minval = 2, maxval = 100, title = "RSI 1 Period")
rsilimit1 = input(20, minval = 2, maxval = 50, title = "RSI 1 Limit")
usersi2 = input(true, title = "Use RSI 2")
rsiperiod2 = input(7, minval = 2, maxval = 100, title = "RSI 2 Period")

usersi3 = input(true, title = "Use RSI 3")
rsiperiod3 = input(14, minval = 2, maxval = 100, title = "RSI 3 Period")

var float lot = na

strategy.close_all()
