I would assume 5 minutes is ok; do it within seconds or fractions of seconds and it becomes an issue. Bots (and a few eagle eyed traders) see the signal and start buying, you withdraw the order with very little of it having been filled, and have potentially jump-started a price spike. You then sell, wait a bit, repeat. You're conning people into thinking you're about to buy and when they get excited, you turn around and start selling.
