Indicator Fix (currency strength metter)

Hi guys,

Today I have an indicator fix job.

Some background about the indicator:

I've ordered currency heat map on the freelance market, as I needed it for my money flow strategy.

There is a very similar tool on the market, but it works with highest TFs only (I wanted it to work on every TF, also needed custom alerts).

One of the developers made this job for me some time ago. Indicator is calculating most currency indexes fine (comparing to the other similar tools), but there is a problem which was not fixed by previous developer.

Indicator can calculate strength/weakness based on the custom pairs (I can put set of pairs in the settings). I'm using 28 major pairs for calculations:

EURUSD,GBPUSD,AUDUSD,NZDUSD,USDCAD,USDJPY,USDCHF,EURCAD,EURAUD,EURNZD,EURJPY,EURGBP,EURCHF,GBPJPY,GBPCAD,GBPAUD,GBPNZD,GBPCHF,AUDJPY,AUDCAD,AUDNZD,AUDCHF,NZDJPY,NZDCAD,NZDCHF,CHFJPY,CADCGF,CADJPY

The problem is that the last pair on the list (CADJPY in this example) is calculating CAD and JPY indexes in the strange way. (Pict1) - Cad +5,1% JPY -5,1% (always opposite results) which is obviously wrong, as it looks like the both indexes are measured on the one pair only. 

If I put a different pair as the last on the list, for example: GBPUSD

So the set of pairs will look like this:

EURUSD,AUDUSD,NZDUSD,USDCAD,USDJPY,USDCHF,EURCAD,EURAUD,EURNZD,EURJPY,EURGBP,EURCHF,GBPJPY,GBPCAD,GBPAUD,GBPNZD,GBPCHF,AUDJPY,AUDCAD,AUDNZD,AUDCHF,NZDJPY,NZDCAD,NZDCHF,CHFJPY,CADCGF,CADJPY,GBPUSD

It will also give opposite results for GBPUSD (GBP+2,8%  USD -2,8%) - Pict2

The problem is that despite in both examples there are the same set of pairs, it gives wrong calculations using the last pair in the settings.

Any ideas how to fix it?

Thank you

Mark
