Question

谁能向我解释为什么 strategy.entry function 没有被执行？ 这旨在成为一个 pine 脚本，每隔一周购买一次资产并跟踪该资产的积累。 我有以下脚本不会产生任何错误，但它不会输入任何交易或实际保存累积变量。 累积变量在 0 和 1 之间切换，它不会递增。

// This strategy buys the asset displayed on the active chart every 
other week.
strategy("Dollar Cost Averaging")

// Set the amount of USD to buy the asset.
investment_amount = 75

// Variable to track accumulation.
float accumulation = 0

// Buy the asset every other week.
if (weekofyear(time) % 2 == 1.0) and (dayofweek(time) == 2.0) and 
(hour(time) == 12.0) and (minute(time) == 0.0)

    // Buy.
    strategy.entry(id = "Buy", direction = strategy.long, 
    qty=float(investment_amount/close))

    // Alternative way of keeping track of the accumulation.
    accumulation += float(investment_amount/close)

我尝试查找简单的 DCA 松脚本，但我只找到了基于指标购买的脚本。 我只想每两周购买一次。

您应该使用第 5 版的 pinescript。 要声明一个浮点数，您必须使用值= 0.0，而不是= 0。然后您必须使用'var'来声明并仅在第一次给出一个值。 在您的代码中，您使用：

float accumulation = 0

每个新柱将累积值重置为 0

这是代码：

//@version=5
strategy("Dollar Cost Averaging")

// Set the amount of USD to buy the asset.
investment_amount = 75.0

// Variable to track accumulation.
var accumulation = 0.0

// Buy the asset every other week.
weektoinvest = (weekofyear(time) % 2 == 1) and (dayofweek(time) == 2) and (hour(time) == 12) and (minute(time) == 0)
if weektoinvest
    // Buy.
    strategy.entry(id = "Buy", direction = strategy.long, qty= investment_amount/close)

    // Alternative way of keeping track of the accumulation.
    accumulation += investment_amount/close
