This been driving me crazy but i think i found a solution for the SUFFIX Trouble.. At least for XAUUSDb c,r etc...
Follow from top left of MT4 Terminal:
1 File
2 Open Data Folder
3 History
4 Symbol Sets
5 Theres gonna be at least 3 suffix files (b,c,r) don't know if you have more but for me it was (b) select the one your XAUUSD uses or any pair you trying to use.
6 Open IT should look something like this and this is what you gonna do JUST delete the (b) or whatever the letter you have AND leave it like [XAUUSD] and SAVE THE FILE. Just save it.

7 Now reset your terminal close it and the open it back. Now load your chart normally with your template and go to the properties of your CSW and just put your pair in the parameters MARKET DETECTOR in this case XAUUSD AND LEAVE IT LIKE THAT. It should work.. and hit OK.
p.s dont know if it matter but im using the [ CSW fix ]
