+===== Settings Files =====
+The Multi-Market script **./bin/mm.js** uses a default settings file **./bin/mm.settings.ini**. You can use it as a reference of all the available parameters.
+**mm.js** always loads the default settings file. Then we specify the parameters with custom settings files or CLI parameter.
+Here we load custom settings file ''mm.in'' and then override some of the parameters:
+    node ./bin/mm.js --settings mm.ini --symbol GBPUSD
+We can give several settings files. The later overrides the previous one.
+    node ./bin/mm.js --settings mm.ini gbpusd.ini
+===== Parameters =====
+The Multi-Market needs several groups of parameters:
+==== Input Data set ====
+<code ini>
+; These perameters serve to resoleve the input collection placeholders
+; Server: Premium, Eightcap, BlackBull, Darwinex, MetaQuotes
+server = Premium
+; The symbol of the original strategy
+symbol = EURUSD
+; Timeframe to download and use.
+; Available values: M1 M5 M15 M30 H1 H4 D1
+period = M30
+</code>
+==== Input collection  ====
+<code ini>
+; Points to one or more collections, or to a collection directory, for validation.
+; Possible placeholders: [SERVER], [SYMBOL], [PERIOD], [YEAR], [MONTH], [DAY]
+input = Coll_[SERVER]_[SYMBOL]_[PERIOD].json
+; Filters the input collections by given text phrases.
+; Useful when the "input" directory contains many collections.
+; Possible placeholders: [SERVER], [SYMBOL], [PERIOD], [YEAR], [MONTH], [DAY]
+input_match =
+</code>
+==== Data parameters  ====
+<code ini>
+; These parameters affect the initial data set and the fetched data
+; Time zone offset in hours. UTC = 0
+time_zone = 0
+; Cut data to maximum bars.
+; Set it to 0 to load all available bars
+max_data_bars = 100000
+; This option is helpful to prevent frequent downloads of data files.
+; It accepts time in *minutes*, where 0 means the option is off.
+; Example: if_missing_or_older_than = 60
+;   It downloads a new data file if the current file is missing or was not updated in the last 60 minutes.
+if_missing_or_older_than = 0
+</code>
+==== Test data ====
+<code ini>
+; One or several servers to load and test
+; Valid server names: Premium, Eightcap, BlackBull, Darwinex, MetaQuotes
+test_servers = Premium
+; One or several periods to load and test
+; Valid period names: M1, M5, M15, M30, H1, H4, D1
+test_periods = M15
+; The symbols to download and use for the MM validation.
+; Example: test_symbols = EURUSD USDCHF GBPUSD USDJPY
+; Use "auto" to allow the program to select the symbols automatically.
+test_symbols = auto
+</code>
+==== Multi-Market tests ====
+<code ini>
+; The count of the Multi Market tests to perform.
+count_of_tests = 5
+; The minimum count of the passed tests.
+; A test is considered as "passed" if it passed the Acceptance Criteria.
+; Must be less than or equal to "count_of_tests".
+min_passed_tests = 3
+</code>
+==== Output collection ====
+<code ini>
+; Output collection filename for a newly generated or validated collection.
+; Possible placeholders: [SERVER], [SYMBOL], [PERIOD], [YEAR], [MONTH], [DAY], [COUNT], [PROFIT]
+; Placeholders can be used as directory names too.
+; Example: output = ./collections/[SERVER]/[SYMBOL]/[PERIOD]/collection.json
+output = Coll_[SERVER]_[SYMBOL]_[PERIOD]_MM.json
+; When "false", adds a suffix if the collection file already exists.
+; When "true", it overwrites the file.
+output_replace = false
+</code>
+==== Account settings ====
+<code ini>
+account_currency = USD
+initial_account  = 10000
