This is a totally new Charbis release operating just on the EURUSD instrument. It uses two indicators: Relative Strength Index (period = 4) and trend lines, which are computed by the strategy itself. It opens short positions when the trendline slope is negative and the RSI is below 70%; symetrically bullish when slope is positive and RSI > 30. The positions are closed when price crosses trendlines. No specific SL nor TP pre-defined: SL is computed for each new position considering the trendline-price distance, and it is moved following the price direction (trailing stop).
