Fugu Flash

Overview

Fugu Flash is a grid-based trading Expert Advisor (EA) for MetaTrader 5 that uses a Moving Average indicator to determine trade direction. The system opens positions in a grid pattern when price moves away from the moving average, with all positions sharing a common take profit target.

Key Features

  • Grid Trading System: Opens multiple positions at predetermined price intervals
  • Moving Average Strategy: Uses MA to determine initial trade direction
  • Shared Take Profit: All grid positions close at a single calculated target
  • Martingale Position Sizing: Optional exponential volume growth
  • Time-Based Trading: Configurable trading windows and day filters
  • State Recovery: Automatically reconstructs grid state after MT5 restarts
  • Direction Filtering: Trade long only, short only, or both directions

Installation

  1. Copy the entire Fugu Flash folder to your MT5 Experts directory:[MT5 Data Folder]/MQL5/Experts/Fugu/Fugu Flash/
  2. Attach Fugu Flash.ex5 to your chart

  • Consider your account balance and risk tolerance before configuring

Recommended Settings

  • Start with conservative grid distance (10-20 pips)
  • Use reasonable maximum trades (3-5)
  • Enable Martingale only with sufficient account balance
  • Test thoroughly on demo accounts before live trading

  • MT5 terminal restart
  • EA removal and re-attachment
  • VPS reboot

This ensures:

  • Existing positions are recognized
  • Take profit levels are recalculated
  • Trading logic continues seamlessly
