you have to treat trading like a business. it is not a job where you are guarantee an income. when you start a business, some month you lose money, some month you make money. it is also why 90% fail when starting a business just like trading. if you can't deal with this. just put your money in an index fund and don't look at it until you are 60 years old.
I totally agreed with what you are saying. I think that's not the main point of my question. My question deals more with "sunk cost" vs "opportunity cost".
I just came back from cardio exercise. And I kinda resolves this dilemma by reframing it as this.
The loss is done and over with. Spilled milk. Sunk cost. There's nothing I can do about the past. I can do something about the future...
Now, I seem to have somewhat of a viable edge(cautiously optimistic). What I can do is apply my edge a few hours a day. Keep risk under tight controls. And the rest of the time focus on my non-trading business. And those few hours a day will compound. I estimate at the current flat rate of earnings it will take me probably 1 - 1.5 yrs to recover all of my prior losses.
Then another thought occurred to me. This is assuming linear growth. What I've noticed is that experience compounds. I would imagine I continue to get better. So those few hours a day compound so that the average winners get bigger and bigger. I hope...
Then there's outlier winners. I've noticed once a week or once a month there is ALWAYS a killer move somewhere in one of the markets I trade. Ride that with size and it will be multiples of my normal winnings. That's what happened in my last run of trades. Small wins. Small wins. Then the last 2 wins were 34x - 100x my average winner respectively. Now, ironically these big winners were almost stressful free in a sense that they were right from the get-go. They are not normal occurrences but they occur often enough in a month. This is when everything lines up perfectly and I load with size and I feel in my gut it's right. Obviously they could go wrong. Then I would get out right away. Tight leash.
Let's say conservatively, I catch one of those big moves once a month. Perhaps I can recover faster than 1.5 years. And it could snowball..
That's the optimistic case.
But to hedge that, I will need to continue to focus on non-trading income stream.
