I have recently started trading in price zones and I have seen it very effective but one should keep in mind about the trendlines and the price channels too or else the price action may change. So here's a short for me in EURCAD, the time period is weekly but as the candle closed below the zone for me its a short position with the stoploss at the high of the zone and the target at the below. As it is a positional trade, I would suggest to exit small quantities at every targets.
