Trading isn't about the successful trade. They come naturally when you know what to look for. In my case, if I'm long I want to see people attacking the offers with little resistance, then I want to see the big guy pulling his bids to trap bots, then I want to see him not get filled.. and hit up again. I also want to see the offers pulling every time it splashes up a little. This comes with muscle memory and watching the ladders which I've spent over 5 years on, so it's hard to explain more in detail for you.
Most of trading is the grind. You want to be able to handle the grind trades with such automation that they never turn into big losers.
Thought process (very simple):
0. What is the context of the day?
-What time is it (near open, afternoon, or close).
-Is correlation in play today?
-What is the price action like (are people hitting up and down, back and forth).
-What is the total volume done so far, is it big or low?
-Are there are any figures coming out later on, and how important?
-Have any figures come out earlier which may entice people to do their orders earlier
-Is there evidence of big players participating right now? If there isn't, why gamble on the hope that they enter?
1. Do I have enough reason to enter this trade or is this 50/50?
2. Where am I wrong? If it trades 4 ticks away, I'm wrong... do I still want the trade? Probably not. At another time, I'm wrong if it trades 1 or 2 ticks away... this is a golden trade!
3. Am I stepping in-front of a train? Sure, it might be running out of steam, but that doesn't mean weak people are also in a position and looking to exit as soon as it doesn't look good for them, squeezing everyone else too.
Note: Most of these are learned over time. It takes about 6-12 months to get the hang of this. For my friends and people I mentor at my firm, it will take about 2-3 months because they get to talk to me every single day and put the pieces of the puzzle together instantly, instead of waiting 1-month to figure it out.
