For example: Code string x = "SMA"; vars MA = series(x(priceClose(), 100)); PS. without using "#define x SMA", only with string var. Thanks Last edited by maxwellreturn; 07/20/19 21:36.

Read this blog article by jcl: https://financial-hacker.com/trend-and-exploiting-it/ The function filter() is redefined many times in a large scale test, using batch scripting. Definitely give it a look. www.vitaltrades.com - andrew@vitaltrades.com
