Summary: BTC K-Range Stabilizer EA is an MQL4 expert advisor for Bitcoin that analyzes candlestick ranges, detects volatility contraction, and enters on range breakouts with volume confirmation. Suitable for H4.
BTC K-Range Stabilizer EA is built specifically for Bitcoin's unique price behavior. Instead of traditional indicators, it analyzes pure candlestick data: range size, body-to-wick ratio, and volatility contraction patterns. The EA identifies periods of low volatility (compression) and enters when price breaks out of the established range with momentum confirmation. A dynamic take profit based on the compression range size and a trailing stop that activates after 1.5x range capture profits while limiting drawdown.
Recommended Timeframe: H4
Trading Logic:
1. Range Detection: Calculate the average true range of last 20 candles. Identify consolidation when current range < 0.55 * average range.
2. Compression Pattern: Require at least 3 consecutive candles with decreasing ranges (volatility contraction).
3. Breakout Entry: When price closes outside the highest high or lowest low of the compression period by at least 1.5x current ATR.
4. Risk Management: Stop loss at opposite side of compression range. Take profit at 2.5x compression range size. Trailing stop activates at 1x profit.
