If you notice that the last three candles show that the market is going up
, this is a good signal to open a buy position. If at least 2 last candles go down, this is a signal for a potential downward trend and you can place a sell position. In order to minimize possible losses you can use such orders as take profit and stop loss. You can place a take profit order after 120 points in case if the prices between the opening and closing of the market did not surpass 80 pips for the last 5 trading days. If the rates surpassed 80 pips for the last 5 days, you can set up the take profit order on 240 points.
