Well, definitely it is. When you're used to the market, you're aware of how it goes and it's like an easy thing to you anymore. That's what happens when we're used to things. Being reliable depends on how good you are, how experienced you are.
And with what you've experienced, everything is going to dependent to you and when you end up with good results, that only means that there's something that you get to understand as you trade.
There's always an advantage if you are already familiar with the market situations, than to start a trading without even a good experience from it. But for me, getting used to the market and learning from all the mistakes we did will eventually contribute to a more successful trading, as we will never be making the same mistakes again. And once we start understanding the market, we can weigh things which strategies will work or not, as we can be more productive and successful traders if we will come to ride the flaws of the market and manage the risk.
