Acessing Multiple Pair in one chart - Relative Currency Indicator (RCI)

Hi everbody. I work on a Relative Currency Indicator (RCI)

I want to develope an chart showing multiple pair in indicator window. For example showing GBPJPY, EURPY, USDJPY together in EURUSD chart.

Currenctly I developed some programs but they are not as good as for my purpose.

I faced some issues.  When I put my indicator in a chart(for exmaple GBPJPY) graph and actual one minute GBPJPY chart is different. When I debug code, I see last values sometmes 0 in indicator window. Also actual graph is not fully syncronised with actual data. There ara GAPS in on the data.

I choose diffrent styles to aces other chart info.

Arraycopyseries. or iClose(), Copyrates().

When first graph drawn correctly, I calculate current values by Symbolinfo() function.

 If I summarise problems 

1- Sometimes last values 0 (Specially when market is volatile or some important news i awating)

2- There are missing data in past data ( althogh they are complete when starting the MT4 indicator)

3- GBPJPY, EURJPY, EURTRY, XAUUSD, XAGUSD returned values have digit problems (e..g. GBPJPY returned form iClose() is 174562 instead of 174.562) 

As last solution I try to develope a file systtem to hold past data and update it indepently from MT4. 

Do yuou faced these problems, or do you have good solutions.

I found a good system and I will share this idea with people help in this topic. 

Currently I can not utilise this idea because uncorrect data.

Thanks in advance
