I have traded very long time, 75% of it manually, but now all systems are automated trading seconds to very long time futures of years in trades, many rollovers. Am firm believer that you must trade manually first before going to automation. Otherwise when it is time to adjust a system, can do it easily.
Better to find one pattern to trade than many, better to under trade, when you profits gone up 500% then add another pattern. One pattern stops from over trading.
And above all, don't show others your best methods.
the beginners should choose the broker which is more appropriate to use all kinds of trading techniques . otherwise trading life will be more difficult.
