In this week’s episode of Trading Talk, we build a simple gap-fill strategy designed to identify market gaps and trade the potential move back toward the previous price level.
This episode covers how to define gap size, add specific logic for JPY forex pairs, and include pyramid entries with a take profit function. The goal is to show how a basic trading idea can be structured into a clear, rule-based strategy that can be tested and refined over time.
Key Points
- We define what qualifies as a market gap within the strategy logic
- We add separate handling for JPY pairs to account for different price formatting
- We build pyramid entry logic to allow additional trades under defined conditions
- We include a take profit function to manage open positions systematically
- We continue developing practical strategy-building concepts for automated trading
Why Gap-Fill Strategies Matter
Gap-fill strategies are built around the idea that when price opens away from a previous level, the market may attempt to move back toward that level. While not every gap will fill, this type of strategy provides a useful framework for traders who want to explore price inefficiencies using structured rules.
In this episode, the focus is not on prediction, but on building a repeatable process. By defining the gap size, setting entry conditions, and managing trades with pyramid logic and take profit rules, traders can begin testing whether this type of setup has potential across different forex markets.
Building Rule-Based Trading Models
A key part of systematic trading is turning a market observation into clear instructions. Instead of relying on discretion, the model needs to know what conditions must be present before it can act.
This gap-fill model helps demonstrate that process by showing how a simple concept can be converted into strategy logic. From gap detection to position management, each part of the system needs to be measurable, testable, and repeatable.
Algo Trading Conference Reminder
This year also marks our 10th annual Algo Trading Conference, where we will be unveiling our Core Framework and building 10 new models based on insights from past speakers.
For traders interested in learning how professional systematic models are developed, refined, and managed, the conference will provide a deeper look into the framework behind our strategy-building process.
