Up and Down Trader Collection: Free MT4 Expert Advisor

Overview

The primary robot, Up and Down Trader, employs a Fisher-style transformation of price action to identify entry points across three different trading modes. It features a spread filter to avoid trading during illiquid conditions and allows users to manage market orders alongside automated signals. Risk management is restricted to fixed lot sizing, as no explicit stop loss or take profit parameters are present in the provided inputs. The collection also includes a dedicated utility to close all positions at the start of a new candle.
