Thanks, have just subscribed to this alert. As for SL. Price may retest the trendline briefly spiking through it and then coming back, not violating the pattern.. It is important that it does not exceed 131 otherwise it is likely that the trend up is still on.
I agree about the SL, My SL trigger will be when the trend line breaks with more then 20 pips. Either way, if the SL will be triggered then I'll look at the graph and decide if to close or not depending on the price's movements
