** or use string indexOf():

if (',OIL,EURCHF,EURUSD,SPG,'.indexOf(','+Ticker+',')=-1) {

** or use Regex:

if 
(!',OIL,EURCHF,EURUSD,SPG,'.test(new RegExp(','+Ticker+','))){

** or an easily explandable switch:

switch(Ticker) {
    case 'OIL': break;
    case 'EURCHF': break;
    ....
    default:
        {do what you wat to do};
};
