You done everything to master the technical side of trading.  Many hours of studying Fibonacci, MACD, and price action.  You've been correlating multiple time frames and are only taking A+ trades.  

After a few weeks of consistent profitability on the sim account, you're ready to start trading live.  You've done your pre-trading preparation, and are ready for market open.  At first, you feel a new level of excitement.  You feel impatient and anxious to get into your first trade.  

Market is open and your pumped!  A few minutes into market open, you see a trade setup.  Click and "order filled", pronounced by your trade matrix.  You feel a rush of adrenalin fill your body, making your palms sweat and heart rate increase.  Immediately, the trade takes your stop loss.  You understand profitable trading doesn't mean you win every trade, and so you move on…

A few minutes later you see another great trade setup.  Another loss… this one starts to tug at your ego.  Your confidence turns to doubt.  When the next trade set up comes around, you hesitate to pull the trigger.  Your bruised confidence has affected a trading decision.  The trade pivots, then blows through your profit target.  Next, you start to think about all those negative thoughts- "Can I really do this?" "I'm not disciplined enough to trade"
