Question

我创建此代码来绘制fib的水平，以查看价格是否超过了这些fib的水平，但是我的代码太长了，有什么方法可以优化下面的水平，

代码按预期工作，但我想以有效的方式减少代码

由于我使用多个if语句，并且每个条形索引使用不同的级别，因此代码变得冗长

请提出建议

level11 = low_range - 1.604 * diff 
level12 = low_range - 1.590 * diff
level13 = low_range - 1.576 * diff
level14 = low_range - 1.562 * diff
level15 = low_range - 1.548 * diff
level16 = low_range - 1.534 * diff
level17 = low_range - 1.520 * diff
level18 = low_range - 1.506 * diff
level19 = low_range - 1.492 * diff
level20 = low_range - 1.478 * diff
level21 = low_range - 1.464 * diff
level22 = low_range - 1.450 * diff
level23 = low_range - 1.436 * diff
level24 = low_range - 1.422 * diff

松脚本在transactionview上绘制fib水平的方法
