WHAT IF THE PRICE HAS MOVED ALREADY AND I MISSED THE ENTRY?
If price has moved against your direction, you can still take the trade. This is because you will be getting a better entry price in the market. If price has moved toward the direction of the trade, your risk will be slightly higher. You can then either wait and see if the price will retrace to entry level, or you can assess your risk to reward and decide if the trade is still worth taking. If not, move on to the next trade. There will always be more.
