Emulating Single-Option Payoffs with Underlying-Asset Rebalancing

Summary

This article describes an expert advisor that emulates single-option positions by mapping option-like levels to orders in the underlying asset and continually rebalancing the position. It introduces a base class for option constructions, stores component options in a list, and updates their combined delta as the underlying price changes. The examples cover long calls, long puts, short calls, and short puts, with configurable sigmoid parameters and delta-normalization ranges. The stated aim is to extend the framework to more complex option constructions.

Illustrations discuss a simulated long-call case that ended with a fixed rebalancing loss of USD 2.39 and a separate long-put example with a USD 5.77 loss; the article relates such losses to the premium that an actual option buyer might pay. It also describes forced expiration at a configured time. These examples show how the mechanism behaved in particular price paths, not a general performance assessment. Emulated options have no upfront premium, and their realized outcomes depend on price movement, time held, rebalancing, and implementation choices.

Key ideas

• The expert advisor approximates option behavior by holding and rebalancing positions in the underlying asset.
• A shared construction class tracks component options and sums their delta as prices change.
• The framework implements long and short calls and puts, with parameters controlling the emulated payoff curve.
• Rebalancing can create losses that resemble an option premium, although there is no premium paid upfront.
• The reported examples depend on specific market paths and do not establish broad strategy performance.
