iClose not working for symbols other than current one

I'm trying to get the current quote for a symbol not in current window. Unfortunately it doesn't work.

I have tried with iClose(mySymbolString, 0, 0), MarketInfo(mySymbolString, MODE_BID), and even SymbolInfoDouble(mySymbolString, SYMBOL_BID).

What I have tried so far:

1.- Any of the 3 above mentioned functions work when using Symbol() (that means, it works with symbol in current chart), but not with other Symbols NOT in current chart.

2.- When using iClose with a symbol NOT using Symbol() (even if the symbol is in current chart!) , but part of "Market Watch", then I get the quote BUT without decimals! (example: EURJPY should be 138.78, but I get 13878 (without decimal))

3.- For MarketInfo() and SymbolInfoDouble(), what I get is just "0", even when using a string with the symbol in current window.
