BB Sniper is a trading expert advisor that implements a scalping strategy based on Bollinger Bands analysis. The advisor is designed for trading on M1 and M5 timeframes.
The core trading logic involves identifying price touches of the Bollinger Bands boundaries. Signal filtering employs two additional confirmations: the Relative Strength Index (RSI) value and Supply/Demand zone analysis across multiple timeframes.
After opening the initial position, the advisor builds a grid of orders by placing limit orders at levels corresponding to Supply and Demand zones. When the price reaches the grid's breakeven level, orders are closed. In case of adverse price movement, positions are closed with loss cutting upon reaching a specified drawdown level.
Version 6.00 includes an improved drawdown calculation mechanism based on balance and equity, along with three grid management modes.
Entry Signals
Buy signal is generated when the following conditions are met simultaneously:
-
price is below the lower Bollinger Band with specified offset;
-
RSI value is at the oversold level (default below 30);
-
price is within the Demand zone.
Sell signal is generated when the following conditions are met simultaneously:
-
price is above the upper Bollinger Band with specified offset;
-
RSI value is at the overbought level (default above 70);
-
price is within the Supply zone.
Grid Order Management
After opening the initial position, the advisor places limit orders at levels determined through Supply/Demand zone analysis. Lot size management can be performed using one of the following methods: fixed lot, progressive lot increase (martingale), or combined scheme with lot variation depending on grid level.
Grid Closing Modes
The advisor provides three grid closing strategies.
Supply/Demand only mode. Closing occurs solely upon reaching the Supply or Demand level. This mode involves waiting for price reversal from a significant level.
Drawdown only mode. Closing occurs exclusively based on drawdown level. Positions close upon reaching 20% drawdown. Emergency closing of all positions occurs upon reaching 30% drawdown.
Combined mode. The advisor waits for the Supply or Demand level to be reached, but positions close when critical drawdown (20%) occurs to limit losses. Emergency closing at 30% drawdown occurs regardless of price position relative to levels.
Profit Control
The following profit fixation modes are available: disabled, upon price reaching the average grid price plus specified points, upon reaching specified profit in US dollars, or combined mode where closing occurs upon the first achieved condition.
