Summary
This article shows how to build a simple session breakout strategy in Profectus.AI.
The idea:
Save the high and low of one trading session
Wait for the next session
Buy if price breaks above the saved high
Sell if price breaks below the saved low
Example used in this article:
Trade New York session breakouts using the London session high and low.
Also known as: session breakout, London breakout, high/low breakout, price action breakout, New York breakout strategy.
This is an educational example, not investment advice. Always export and test in MT5 Visual Mode before using the EA on demo or live.
What the strategy does
The EA first records two price levels:
London_High London_Low
Then, during the New York session, it checks whether price breaks those levels.
If price crosses above London_High, the EA can open a buy trade.
If price crosses below London_Low, the EA can open a sell trade.
Trading logic
1. Create two variables
Create these variables:
London_High = 0 London_Low = 0
These variables will store the session range.
2. Save the London high and low
Use Run at Time at the end of the London session.
Example:
Run at Time: 15:00
Then use Modify Variables:
London_High = Highest Candle High from Candle ID 1 to Candle ID 8 London_Low = Lowest Candle Low from Candle ID 1 to Candle ID 8
This example assumes you run the EA on the 1H timeframe and want to look back over the last 8 completed hourly candles.
If you use another timeframe, adjust the candle range.
Example:
1H chart, 8 hours = Candle ID 1 to 8
30M chart, 8 hours = Candle ID 1 to 16
15M chart, 8 hours = Candle ID 1 to 32
3. Trade the breakout during New York
Use Run in Session for the New York session.
Example:
Run in Session: 15:00 to 21:00
Use your broker/server time, not your local time, unless they are the same.
Buy logic
During the New York session, check:
Price crosses above London_High
Then add Count Trades:
Buy trades = 0
Then execute:
Buy Now
Simple structure:
Run in Session → Trade Rule: Price crosses above London_High → Count Trades: Buy trades = 0 → Buy Now
Sell logic
For sells, use the opposite logic:
Price crosses below London_Low
Then add Count Trades:
Sell trades = 0
Then execute:
Sell Now
Simple structure:
Run in Session → Trade Rule: Price crosses below London_Low → Count Trades: Sell trades = 0 → Sell Now
Main blocks used
Run at Time
Used to save the London session high and low at a specific time.
Modify Variables
Stores the calculated session high and low into variables.
Run in Session
Only allows breakout logic to run during the selected trading session.
Trade Rule
Checks whether price crosses above or below the saved session level.
Count Trades
Prevents duplicate buy or sell trades.
Buy Now / Sell Now
Opens the market trade when the breakout condition is valid.
How to use it
Create
London_HighandLondon_Lowvariables.Use Run at Time at the end of the London session.
Store the highest high and lowest low of the session.
Use Run in Session for the New York session.
Add buy logic for a break above
London_High.Add sell logic for a break below
London_Low.Add Count Trades before Buy Now and Sell Now.
Export the EA as EX5/MQ5.
Test it in MT5 Visual Mode.
In Visual Mode, check that the saved high and low match the correct session before judging the trade logic.
Make it your own
You can adjust this strategy by changing:
Which session range you save, for example Tokyo, London, or New York
Which session you trade afterward
The number of candles used to calculate the high and low
The timeframe used in MT5
Whether you allow one buy, one sell, or only one total trade per day
Stop loss and take profit logic
Spread filter
Session filter
Draw on Chart blocks to visualize
London_HighandLondon_Low
For better debugging, draw both levels on the chart before testing entries.
Conclusion
A session breakout strategy uses a previous session’s high and low as breakout levels.
In this example, the EA saves the London session range, then trades breakouts during the New York session.
The core logic is simple:
Save session high/low → Wait for next session → Trade break above or below the range → Prevent duplicate trades
Always export and test in MT5 Visual Mode to confirm the levels, timing, and entries behave correctly.
