Pine script 与策略信号相比，警报信号计数不同

我试图根据以下附加的研究生成警报。警报已生成，但与策略信号不同。今天我为TCS生成了信号。根据策略，今天有5笔交易，但在警报方面，我得到了几乎12-15个信号。我不知道我在哪里失踪了。如果有人知道这件事，请帮助我

作为参考，我附加了一个快照

这是一项研究

plot(val, title="type", color=color.black)

//defining plots above are required only for the purpose of passing dynamic variables to alerts. Their color is set to 'na' so that they don't display on the screen.

alertcondition(val !=0 or not sessionOpen, title='Alert', message='{{ticker}}, price = {{close}} OrderType={{plot("type")}} at time = {{time}}')

window（）=>时间>=开始和时间可能的原因在于金字塔-策略不进入相同的位置，您的研究-感谢您的回答。我试着用金字塔来调整我的策略。不过，我还是遇到了同样的问题。您也可以尝试上述脚本。我认为问题出在警报的
not sessionOpen
条件下。当
not sessionOpen
为真时，请注意此问题策略不会发送订单，但会触发警报
