Trading Hours:
1. First session: 8:30–14:15 CET.
2. Second session: 14:45–21:55 CET.
It must be possible to enable/disable each session's start and end times.
Day Filter:
Each weekday must be individually activated/deactivated via a checkbox, and trading times must be set separately for each day.
Risk-Reward Ratio (RRR):
* Default = 1, but adjustable.
Maximum Stop-Loss:
* Default = 30 ticks, with an option to set other values.
BreakEven Switch:
* Enable/disable via checkbox.
* Configure BreakEven placement (e.g., BreakEven at 50% of the initial stop loss).
Trailing:
* Enable/disable via checkbox.
* Configure trailing distance as a % of the initial stop loss.
* Configure trailing start as a % of the initial stop loss.
* Options: Trailing to BreakEven, Trailing from BreakEven, or Continuous Trailing.
ATR Indicator (5):
* No order is triggered if the ATR value is below 20.
Order Holding Duration:
* Adjustable, default = 5 minutes
Instrument/Symbol:
* Must be universally applicable to any instrument (Crypto, Forex, Indices, etc.).

Rules
Trading Sessions:
* two sessions per day: 
* First session: 8:30–14:15 CET.
* Second session: 14:45–21:55 CET.
Chart:
* Timeframe: 3-minute chart.
* The strategy must work for any instrument.
Entry Rules:
* ATR Indicator (5): No order is triggered if the value is below 20.
* Identification of a signal from the "Keltner Channel" (KC): 
o After the price exits the KC, it re-enters and closes within it.
o Buy-Stop Order: Price exited through the "Lower" line and re-entered KC.
o Sell-Stop Order: Price exited through the "Upper" line and re-entered KC.
* Place a Buy-Stop Order at the high of the signal candle plus a buffer.
* Place a Sell-Stop Order at the low of the signal candle plus a buffer.
* If a trade is already active and a new signal appears, it is ignored.
* For a Buy-Stop Order, the price must close inside the KC after re-entering KC.
* For a Sell-Stop Order, the price must close inside the KC after re-entering KC.
Buffer Calculation Based on Signal Candle Size:
* < 10 points: Buffer = 1 point above high / below low.
* 10 - 20 points: Buffer = 2 points above high / below low.
* = 20 points: Buffer = 3 points above high / below low.
Stop-Loss:
* Set on the opposite side of the signal candle: 
o Buy-Stop Order: SL = Low of the signal candle plus buffer.
o Sell-Stop Order: SL = High of the signal candle plus buffer.
Take-Profit:
* TP is triggered when: 
o The price reaches the KC base line OR
o A 1:1 RRR is achieved.
Trailing-Stop Logic:
* Enable/disable via checkbox.
* Configure trailing distance as % of initial stop loss.
* Configure trailing start as % of initial stop loss.
* Options: Trailing to BreakEven, Trailing from BreakEven, Continuous Trailing.
BreakEven Switch:
* Once price reaches 50% of the initial SL, SL is set to the entry price.
* The BreakEven percentage (e.g., 50%) must be adjustable.
Order Management:
* Position size calculation based on dynamic money management (% of account balance): 
o Risk amount per trade (€) / Stop-Loss in points.
* Adjustable order holding duration (e.g. 5 minutes).
* All active trades must close automatically at 21:59 CET (adjustable).

Special Cases:
No trade is executed if:
* A trade is already active.
* The signal candle size including buffer exceeds the distance between the order level and the KC base line (RRR < 1).

Programming Requirements
Input Parameters:
* Money Management: Selectable between fixed lot size or dynamic money management (adjustable).
* Day Filter: Monday, Tuesday, Wednesday, Thursday, Friday (individually selectable).
* Session Times: Start and end times per session with enable/disable option (adjustable).
* Order Holding Duration: Default = 5 minutes; Enable/disable (adjustable).
* Trailing Percentage: Default = 50% of initial risk; Enable/disable (adjustable).
* BreakEven Switch: Default = 50% of initial risk; Enable/disable (adjustable).
* EA must be universally applicable, particularly in terms of money management and different decimal places (Indices, Forex, etc.).
Logic:
Time Conversion:
* Convert session times to UTC.
* Ensure correct handling of daylight saving and standard time.
Signal Candle Recognition:
* A candle qualifies as a signal candle if the price exits the KC and then closes inside it.
Order Logic:
* Buy-Stop Order: Placed at the high of the signal candle plus buffer.
* Sell-Stop Order: Placed at the low of the signal candle plus buffer.
* SL: Opposite side of the signal candle (or max SL if adjusted).
* TP: Price touches the KC base line OR 1:1 RRR is achieved.
Trailing-Stop Logic:
* Once 50% of TP is reached, adjust SL: 
o New SL = Entry +/- (initial SL * trailing percentage).
BreakEven Switch:
* Once 50% of TP is reached, set SL to BreakEven = Entry price.
Order Management:
* Trade only within session hours.
* Consider order holding duration.
Exceptions:
* If the signal candle size exceeds 50 points, no order is triggered.
* If a second signal appears during an active trade, it is ignored.
* If a second signal appears during an active order, cancel the first order and place a new one based on the second signal candle.
