Thats not a wise thinking that you will stop your trading while you get lose some pips, wise thinking will be like that just you have to do make analysis yourself and you must use Stop loss which may can minimize your loss on trading that where your account can be washed there you will minimize your lose and that may helps to stay on market for long time. Besides using stop loss you must use take profit that sometimes market moves ups and down that when your trade goes to your targeted price automatically the trade will be closed and that will be super thinking for everyone.
