BigVaran

BigVaran is an Expert Advisor (trading robot) and a set of supporting indicators / libraries for MetaTrader 4 (MQL4), with partial compatibility elements for MetaTrader 5 (MQL5).

It implements a trend-following / breakout strategy based on:

• Adaptive Price Bands (APB channel)
• Fast and slow Triangular Moving Average (TMA) lines
• Impulse filters and false breakout rejection logic
• Position management with trailing stop and risk control

The strategy aims to capture strong directional moves while avoiding ranging / choppy market conditions.

(Replace with real chart screenshots showing entries, channel, TMA lines and trades)
