Just found
the script which are saving all currency, spread and so on on excel file. But this script is working very slowly.
The
other script from KIMIV is doing the same: all simbols information in csv file in /file folder (including spreads).
Besides, it was realized in CyberiaTrader EA (we have one public and one elite thread about this EA).
And this market information about every broker is related to MarketInfo function in Metatrader. Just open MetaEditor and did search concerning MarketInfo.
Of course it may be good if somebody created simple indicator or script which will show all the infor on the chart.
