Pip value has everything to do with managing your risk, but you would need to identify your trading goals for some clarity. But just for conversation's sake, let's say you open an account for $1,000.00. Say your risk is the standard 2% per trade. With an account that size, you could trade up to $3 pips. But with the 2% risk, rounded up a tad you would only have 6 pips for a stop. Ratchet that down a bit to a buck a pip, your stop moves up to 20 pips. With either option there, you would most likely be looking at getting stopped out quickly. Take it to $0.10 pips, and you would be looking at a 200 pip stop loss. Which one gives you the best option for a positive outcome? Again, it depends on your personal goals, and quality of entry signals.
