The last-mentioned strategy type is investing that is usually associated with long-term trading. One of the ways to trade this strategy is to use the Supply and Demand Multi Timeframe Indicator that shows the zones of Demand and Supply that have been formed by a fractal price action pattern.
The basic idea behind it is to use it on Daily charts and above to enter Long trades when the price enters the Demand zone formed by the indicator. The target for that trade is the opposite Supply zone. The stop-loss could be placed beyond the lower edge of the demand zone.
For Sell trades it is the vice versa set up – when the price enters the Supply zone, the Sell trade should be executed with the target at the opposite Demand zone and the stop-loss slightly above the Supply zone.
For this strategy there are also two approaches available: you can either set and forget, i.e. enter the trade, place Stop-loss and Take-profit and wait till price hits one of them, or periodically monitor how the trade goes and trail the stop or at least move it to break even to protect the profit.
