The strategy works. But emotions override it. According to market data from Brazilian studies conducted between 2012 and 2017, 97% of traders who persist for more than 300 days end up losing money. It’s not because they don’t recognize patterns —it’s because their emotions take control the moment they execute.
Oscar Bonilla sums it up with a phrase that belongs on every trader’s wall:
Trading is 95% psychological. 5% technical. And this is the battle you have to win—right here inside.

Fear #1: Fear of Being Wrong
"Should I? Shouldn't I? Is this really the ideal moment to jump in?" This self-doubt paralyzes you. A trader sees the setup, recognizes the pattern, but hesitates because they don’t feel 100% certain.
The reality is that no single trade comes with absolute certainty. Even the world’s top traders are only right 40% to 60% of the time. The edge isn't about being right every time; it's about making more when you're right than you lose when you're wrong.
Antidote: Practice with low risk. Oscar recommends starting with penny stocks priced between $0.10 and $0.20 per share. With just $10 to $20, you can practice execution for a whole year, removing emotional pressure while building the habit.
Fear #2: Fear of Losing Money
This is the most common fear and the most studied by science. Psychologists Daniel Kahneman and Amos Tversky demonstrated in their Prospect Theory that the pain of a loss is felt roughly twice as intensely as the pleasure of an equivalent gain. Losing $100 hurts twice as much as making $100 feels good.
This cognitive bias, known as loss aversion, causes traders to cut winning trades short (out of fear the gain will disappear) and hold onto losing trades for far too long (out of fear of realizing the loss).
Antidote: Set a non-negotiable risk parameter. Oscar teaches the 2% rule: never risk more than 2% of your capital on a single trade. If that percentage still triggers anxiety, drop it to 1% or 0.5% until you hit the sweet spot where emotion drops to zero.
Respect your risk level. Disregarding it is like jumping off a cliff.

Fear #3: Fear of Missing Out (FOMO)
FOMO: Fear Of Missing Out. "The plane took off without me." You see a stock surging and feel anxious because you're not in the trade. This anxiety leads you to jump into setups without analysis or a plan—usually at the worst possible moment, right as the move runs out of steam.
Antidote: Take a breath. Evaluate whether there's real technical potential. And remember a fundamental truth of the market:
The market opens every day. There will always be another opportunity.
— Oscar Bonilla, PhD
Fear #4: Fear of Leaving Money on the Table
"I'm up $500, but what if it keeps climbing and I miss out on another $500?" That's greed disguised as FOMO. You can't bring yourself to close a winning trade because you always want more.
Antidote: Use a trailing stop —an order that automatically adjusts upward as the price rises, locking in profits. If the price reverses, the order triggers and locks in your gains without forcing you to make an emotional decision about when to exit.
Risk Level: Your Emotional Shield
Oscar uses a scale from 0 to 100. At 0 is the trader terrified of losing a single dollar (scared money). At 100 is the gambler who doesn't care about losing it all. Neither extreme works.
Professionals operate in the middle ground where emotion is non-existent. Oscar compares it to learning how to drive: first you practice in an empty parking lot, then in a quiet neighborhood, and only after mastering that do you hit the highway.
Why You Shouldn't Use Simulators or Copy Trades
Simulators: They don't generate real emotions. Your heart doesn't race; your palms don't sweat. It's like practicing boxing without getting hit —when the real punch lands, you won't know how to react.
Copying trades: It makes you a line cook, not a chef. If someone changes the ingredients, you won't know what to do.
If you focus on winning, you're validating your scarcity mindset. If you focus on not losing, the natural outcome is winning.
— Oscar Bonilla, PhD
This shift in mindset is perhaps the most counterintuitive lesson of all: successful traders don't focus on making money; they focus on preserving it. When your risk management is flawless, profits follow naturally.
