This is actually called psychic levels of round numbers. They only depend on market's psychological movements that market would stop at round numbers ending in zero, for example, 1.3200 and then 1.3220, then 1.3250 and then 1.3280. They only earn from sell orders so if market has come down to one psychic level it would descend down to next psychic level eventually. I have read about this strategy before many times with slight changes here and there but have never tried it ... now jiching's claim for it to be 100% safe makes me think again about it ... but I am convinced that there is nothing 100% in forex so how could it be. But still it would be useless to say anything without testing.
