Check out the Candle Trail video below. I placed a sell order on EUR USD 1 MIN Chart.
The robot trailed the sell order by placing stop loss at the highest high of the last 5 candles. Setting allows you to customise the candle lookback and also add an offset value. Best practice here is to study the currency pair, if its a volatile pair like GBPJPY or GBP USD then a higher lookback period is prefered. Second would be the timeframe you are trading- on lower time frames use a higher look back period and for smaller timeframes (H1,H4,Daily) use a shorter lookback period.
You can change the settings to find the last swing high or low.
