I placed an order for entering long at 3374 in the morning. The price actually reached my price and headed to 3375 towards the end of morning session. My position was never filled and closed at 3375. It opened with a gap in the afternoon at 3384 with the low of 3379 and it never plunged to my price of 3375. You maybe right in placing a price when trading, but the slippage could kick you out of the trade.
Lesson Of This Trade: I should place 2 prices or more instead of just 1 price
