Ordinarily, trading pre-market is too slow. Sitting in a trade for an hour waiting for action increases your risk. As long as volatility exists, you should be fine to trade. Review your charts to see volatility associated with Asia and Europe, for example. In our video, you’ll see a number of Trade Scalper signals that happened before the market “opened” at 9:30 a.m. EST. If the market moved during that time with decent volatility, do feel free to trade.
In summary, trade pre-market is permissible when conditions are volatile enough. Such conditions may be present around the open of those exchanges or instruments/markets. But, be aware that the first 15 minutes or so may subject you to greater risk. Indeed, the first 15 minutes are a volatile time.
