Emulating Complex Option Strategies and Visualizing Delta Levels
Summary
This installment develops an options-emulation expert advisor for MetaTrader 5 and adds chart visualization of option levels. It explains how to convert target delta levels into underlying-price levels by searching above or below a strike with the bisection method. The search relies on the option construction’s delta changing continuously and monotonically across the chosen working range; separate calculations handle the two sides because their levels need not be symmetrical. The levels are then drawn as chart lines and labels for monitoring the underlying price against the simulated structure.
The article also describes organizing level objects and option structures with reusable classes, and applies the framework to multi-leg strategies, including a short strangle with different put and call strikes. It provides implementation details and supporting MQL5 files, but the excerpt does not offer quantitative performance evidence or a full risk analysis of these strategies. The option structures are emulated using the underlying asset, so their behavior depends on the model assumptions and should not be taken as evidence of live option execution or results.
Key ideas
- Target option deltas can be translated into underlying-price levels with iterative bisection search.
- Upper and lower option levels are calculated separately because their relationships to the strike may differ.
- Chart lines and labels help visualize the underlying price relative to the simulated option structure.
- Object-oriented classes make it possible to assemble and monitor multi-leg emulated strategies such as short strangles.
