Fixed-Bound FIL Grid Trading with Geometric or Arithmetic Levels

Summary

This long-only FIL strategy places a fixed grid between configurable high and low prices. It offers geometric spacing, which keeps percentage gaps more consistent, and arithmetic spacing, which keeps absolute price gaps consistent. When a bar closes down through a level that is not already owned, the strategy opens a position sized from an equal share of the total investment. When price later closes up through the next higher level, it closes that position. The script includes chart displays, status information, a date filter, and webhook alerts for a bot.

The document gives implementation details and example defaults, including 36 levels, a 0.7099–1.0151 price range, and a 15-minute FIL perpetual market calibration. It does not provide performance results or evidence that the defaults generalize. The strategy deliberately has no stop loss or trailing exit; it relies on the grid bounds and allocated capital as structural limits. Price falling below the grid may leave positions open, and live alerts, fees, slippage, and bot configuration need careful evaluation.

Key ideas

• The strategy buys when a bar closes down through an unowned grid level.
• It closes a grid position after price crosses upward through the next higher level.
• Grid spacing can be geometric or arithmetic, and investment is divided across levels.
• The design has no stop loss or trailing exit and may retain positions after price leaves the grid.
• Webhook alerts connect entry and close events to an external bot.
