i have been using this method for 2 months and gives me 100% profits (zero loss). i never put SL for my pending orders but i prepare balance 150-200 pips for each PO. in this strategy, i don't notice any news, i don't care with low, medium, or high impact news.
the important thing is don't force if the price don't touch our pending orders. i usually put pending orders for 5 pairs, sometimes only one pair is touched, sometimes two, or three, or five pairs...
