😣 전략이 문제일까요, 제가 문제일까요?

Based on what you told, i think that you simply overtrade. And the fact it worked before within today. But you forced trades 'before' open - totally not a good time to trade most of the day. (The moment market opened, price moved quite fine).
The second problem is that you "scaled". That is the very common problem with traders who have small capital and want big gain (i've been there done that, blew up countless accounts). Every strategy, every setup - no matter how profitable it is - will have a losing streak. Do u know that even with the 50% winrate system, you can still have 5-7 losses in a row??
I tried to eliminate that by refining setups. But it will always be there. Losing streak is inevitable. Period. Thats why its a probability game. You can minimize the damage, but cannot get rid of it (trust me, i tried soooo many dif ways).
So, how do u cope with this situation?
There are a few i wanna add, and hope it helps u somehow:
1. If u use volume profile, go 1 strp further, study market profile, delta profile to understand context better. Volume profile alone is totally not enough (it only works best with htf trending market. In this choppy market like this week, nope).
2. I dont know how do u confirm entry setup, but if you can have THAT much entries today, you probably should refine it and reduce the number of entries.
3. This is basic, yet the most effective - even tho you might not like it - SIZE DOWN. The problem is not about winning (you can win), it is about how to keep profit after losing. You DEFINITELY will have another losing streaks. And with the speed of your scaling, you must blow up. The losses after winning are bigger than initial losses. That will fk up your psychology real quick. You were wrong right at the moment you let your risk out of control and you WON 700$. thats too big for the day with initial 100$ (even when you have several thousands to deposit next).
So, just reduce the size. Slow down. Scale gradually. Some winners are not enough to prove true edge and consistency.

What i said is from the bottom of my heart, as a person who was just like you too many times. Truly hope u get pass this phase.

Yikes.

Started with $100, turned it into $700 today trading gold with my VWAP Wave + volume profile setups… then lost half my account in a few trades. Setups felt right, but my execution obviously wasn’t perfect. Feeling frustrated and questioning if it’s the strategy or just me. How do you bounce back from days like this?

the $100 to $700 back to $50 cycle is super common and it's almost always about how your emotions shift after a hot streak, you start sizing up because it feels like you can't lose and then when the drawdown hits you're trading from frustration instead of clarity. i wouldn't ditch the strategy yet because right now you're making that decision from a really emotional place, which is the worst time to evaluate anything. go back to the absolute smallest size you can, track every trade with screenshots and notes for 2-3 weeks, and just focus on following your rules exactly without worrying about the P&L. the data will tell you if the strategy works or if you need to change something, but your gut can't tell you that right now because it's clouded by frustration. you already recognize it's a you problem which puts you way ahead of most people honestly.
