Haha yes I remember these days. They were very frustrating and took me a while before I realised where I was going wrong. What you described: taking loose trades after you’ve had a few winners can really affect your profitability. Worse than that, if you dont follow your rules or have the insight you could even hold onto a bad trade and blow your account.
What I found is, it is not greed but complacency. This complacency presented by making me believe that I could make money regardless of the strategy and therefore I would have a SL further away. As if I have control over the market and it’ll do what I want.
A few winners in a row and you also start feeling that the next trade is a free trade as you are only risking profits. This is why a trading journal or reviewing your trades is important. It focuses your attention to why you took the trade and was it part of your plan. You have to remind yourself that each trade has nothing to do with the one before it or after, they are independent. Therefore regardless of the winners or losers, keep trading your strategy.
I find trading to be like a job that can only be done with one mindset. If you relax or forget you are against the market then you will be proven wrong.
