Fully working EA needs one new trade EXIT rule.

New add-on instructions for existing MT4 EA.

Each trade placed by this EA contains an Order Comment which identifies the Bollinger Band settings and TimeFrame used for opening that particular trade.

Order Comment examples: 

“202.5M15+15466_73450_315_1” 

or 

“202.5M1-74115_1234_231190_1”

Order Comment structure:

First two symbols (example: “20”) identify the Bollinger Band Period used for this trade.

Next three symbols (example: “2.5”) identify the Bollinger Band Deviation used for this trade.

Starting from the 6th symbol and ending immediately before either “+” or “-” is a substring identifying the TimeFrame used for this trade.

Possible TimeFrame values: “M1”, “M5”, “M15”, “M30”, “H1”, “H4”, “D1”

Important note: If the substring starts with “M1”, it may represent either:

“M1” 

or

the beginning of “M15”

All symbols starting from and including “+” or “-” are required for other parts of the existing EA and must NOT be modified, removed, or used for this new add-on logic.

All existing EA logic currently works only on candle closures for the related TimeFrame and NOT on every tick.

This new add-on must NOT change, remove, or interfere with any existing EA logic.

This add-on only introduces one additional exit rule.

For each individual trade, whichever happens first must close the trade:

Stop Loss

existing/main EA exit rule

new add-on exit rule

New EA input setting: Name: “Opposite BB touch threshold”

Input values:

0 = disabled (no new exit rule)

1 = close the trade after the first opposite BB touch

2 = close the trade after the second opposite BB touch

3 = close the trade after the third opposite BB touch

etc.

Maximum allowed input can be set to 1000 if required.

Definition of “Opposite BB touch”:

For BUY trades: A touch occurs when a fully closed candle of the TimeFrame identified from the Order Comment has:

Candle LOW price lower than the LOWER Bollinger Band using the Bollinger Band Period and Deviation identified from the same Order Comment.

For SELL trades: A touch occurs when a fully closed candle of the TimeFrame identified from the Order Comment has:

Candle HIGH price higher than the UPPER Bollinger Band using the Bollinger Band Period and Deviation identified from the same Order Comment.

Important: Trade direction (BUY/SELL) cannot be identified from the Order Comment and must be determined from the actual order type.

Candle range used for counting touches:

Start counting from the FIRST FULLY CLOSED candle AFTER the trade entry candle.

End counting at the latest fully closed candle (shift 1).

The trade entry candle itself must NOT be included in the count.

New exit rule: 

If the total counted “Opposite BB touches” for one individual open trade becomes equal to or greater than that trade’s “Opposite BB touch threshold” input value, then ONLY that single trade must be closed immediately.

End of instructions.
