我有一个语法问题，输出如下:
Error en 12:0 Syntax error at input '='.
特别是在这部分代码中:
// Calculate EMA values
ema_periods = input(title="EMA Periods", type=input.integer, defval=string(9, 21, 50, 100, 200))
ema_values = array.new_float(size = array.size(ema_periods))
for i = 0 to array.size(ema_periods) - 1
ema_values[i] = ema(close, ema_periods[i])
错误如下:图片错误
完整代码如下:
//@version=4
study("Solfeggio Waves Dashboard")
// Define Solfeggio waves frequencies
var int[] frequencies = array.from(174, 285, 396, 417, 528, 639, 741, 852, 963)
// Calculate EMA values
ema_periods = input(title="EMA Periods", type=input.integer, defval=string(9, 21, 50, 100, 200))
ema_values = array.new_float(size = array.size(ema_periods))
for i = 0 to array.size(ema_periods) - 1
ema_values[i] = ema(close, ema_periods[i])
// Calculate the percentage of positive and negative Solfeggio waves
var float[] positive_percents = array.new_float(size = array.size(frequencies))
var float[] negative_percents = array.new_float(size = array.size(frequencies))
for i = 0 to array.size(frequencies) - 1
positive_count = 0
negative_count = 0
for j = 0 to array.size(ema_values) - 1

positive_count := positive_count + 1

修复控制台输出中显示的问题。
您需要使用array.set()函数来设置数组的值。
array.set(id, index, value) → void
id(数组)数组对象。
index (integer)要修改的元素的索引。
value (float, string, label, line)要设置的新值。
