Configuring Leverage and Margin Calls in Pine Script Strategies

Summary

This educational example explains how a Pine Script strategy can model leveraged position sizing and broker margin requirements. For percent-of-equity sizing, the author describes scaling the order percentage by the leverage multiple: using 3000% represents 30 times the account equity allocation. Separate long and short margin parameters represent the required margin assumption; the example combines 30:1 leverage with a 50% requirement. The author stresses that margin requirements vary by broker.

The sample strategy uses stochastic crossovers to enter long or short positions and exits after a fixed profit measured in ticks. It also allows extensive pyramiding, so it serves as a demonstration of strategy settings rather than a complete risk-controlled trading system. The text explains that simulated margin calls can close positions partly or fully and prevent unaffordable additional entries. It warns that reaching a margin call indicates a risk-management problem. No performance evidence is provided, and the sample’s sizing, pyramiding, and take-profit-only exits should not be treated as guidance for suitable live leverage.

Key ideas

• Percent-of-equity order sizing can be scaled to represent a chosen leverage multiple in the strategy settings.
• Long and short margin parameters model required margin, which the document says varies among brokers.
• Backtester margin logic can reject additional entries or liquidate some or all of a position.
• The example pairs stochastic crossovers with a fixed tick-profit exit and allows pyramiding.
• The document presents the script as educational and warns that a margin call signals inadequate risk management.
