 I've been trying to write a PCF Custom Percent True Indicator that will spike when any three of the following four indicators get within 1.5% of each other.  
8 day Simple MA, 20 day Simple MA, 50 Day Exponential MA and 200-day Exponential MA.  
Any help would be greatly appreciated.  The formula I've written says it takes 1001 days to calculate so I've obviously done something wrong...
Thank you for your time.

 No, that doesn't necessarily mean there is anything wrong. The 200-Period Exponential Moving Average would require about that much data for its calculations. Here's what I come up with (it's probably possible to make something shorter):

(AVGC8 + AVGC20 + ABS(AVGC8 - AVGC20) + 2 * (XAVGC50) + ABS(AVGC8 + AVGC20 + ABS(AVGC8 - AVGC20) - 2 * (XAVGC50))) / (AVGC8 + AVGC20 - ABS(AVGC8 - AVGC20) + 2 * (XAVGC50) - ABS(AVGC8 + AVGC20 - ABS(AVGC8 - AVGC20) - 2 * (XAVGC50))) <= 1.015 OR (AVGC8 + AVGC20 + ABS(AVGC8 - AVGC20) + 2 * (XAVGC200) + ABS(AVGC8 + AVGC20 + ABS(AVGC8 - AVGC20) - 2 * (XAVGC200))) / (AVGC8 + AVGC20 - ABS(AVGC8 - AVGC20) + 2 * (XAVGC200) - ABS(AVGC8 + AVGC20 - ABS(AVGC8 - AVGC20) - 2 * (XAVGC200))) <= 1.015 OR (AVGC8 + XAVGC50 + ABS(AVGC8 - XAVGC50) + 2 * (XAVGC200) + ABS(AVGC8 + XAVGC50 + ABS(AVGC8 - XAVGC50) - 2 * (XAVGC200))) / (AVGC8 + XAVGC50 - ABS(AVGC8 - XAVGC50) + 2 * (XAVGC200) - ABS(AVGC8 + XAVGC50 - ABS(AVGC8 - XAVGC50) - 2 * (XAVGC200))) <= 1.015 OR (AVGC20 + XAVGC50 + ABS(AVGC20 - XAVGC50) + 2 * (XAVGC200) + ABS(AVGC20 + XAVGC50 + ABS(AVGC20 - XAVGC50) - 2 * (XAVGC200))) / (AVGC20 + XAVGC50 - ABS(AVGC20 - XAVGC50) + 2 * (XAVGC200) - ABS(AVGC20 + XAVGC50 - ABS(AVGC20 - XAVGC50) - 2 * (XAVGC200))) <= 1.015
