我最近刚开始使用 pine scrip，我写了这段代码回测了一个策略，但是 strategy.entry() 函数似乎不起作用。我什至改变了它，使它与其余的代码完全无关，它仍然不起作用。我想知道是否有人知道什么可能会阻止我的 strategy.entry() 根本不工作。

valuewhen_1 = ta.valuewhen(pivotHigh, high[Period], 1) // return the most recent occurence of a condition; in this case, the most 2nd recent time (so the last-last time) there was a pivot high
valuewhen_2 = ta.valuewhen(pivotHigh, high[Period], 0) //returns the most recent pivot high
higherhigh = na(pivotHigh) ? na : valuewhen_1 < valuewhen_2 ? pivotHigh : na //higher high returns the price of the most recent pivot high IF it is greater than the last pivot high
lowerhigh = na(pivotHigh) ? na : valuewhen_1 > valuewhen_2 ? pivotHigh : na
