Well Martin - expert for MetaTrader 5

Well Martin EA is based on two indicators: Bollinger Bands and ADX. It is designed for use on a tranquil market.

After a Stop Loss, the EA increases the lot by KLot coefficient until it reaches the maximum value — MaxLot. Then the lot returns to its start size — Lot.

The EA has Stealth Mode in which the stops are visible only to the user.

When breaking through the lower Bollinger Bands boundary, the EA opens a Buy order, when breaking through the higher boundary, it opens a Sell order.
