Funds dissolving "brain bug" Bankruptcy-free "casino theory"

“I did it again…”

The fundamental reason you blow through funds in trading is the collapse of position sizing driven by emotion.

Sitting with head in hands in front of the charts,a night where all your funds keep melting away as you just watch, you must remember the despair as cold sweat runs down your back.

You had vowed to hit the emotional brakes, but somehow on the next trade you increase your lot size, and before you know it the account balance is wrecked. Won’t you end that “high-spirited, willpower-driven trading” once and for all?

In fact, the reason professionals win isn’t because their minds are stronger.

Because they are simply running the mathematically inevitable system (casino theory) in a calm, methodical way.

This time, from Tresta’s research theme ④ “Science of Casino Theory,” we bring you the “truth of absolutely never going bankrupt with lot sizing,” obtained by multiplying expected value, win rate, and profit-to-loss ratio.


1. Why does your capital melt away in an instant?

No matter how high your win rate, traders continue to lose a large portion of their account with a single defeat.

The root cause is trading with intuition (gambling) and abandoning the shield of proper capital allocation. In the professional hunting grounds of the market,a lot size without mathematical justification is equivalent to choking yourself.

2. The casino dealer’s “unbreakable” trick: the psychology of expected value

Casinos don’t profit from luck; they profit by embedding the house edge (the casino’s advantage) into every game, yielding enormous profits.

What traders should aim for isn’t becoming a prophet, butto thoroughly calculate their own positive expected value.

“The absolute equation: win rate × average win > loss rate × average loss”, once understood, your trading transforms from gambling into a “business.”

So, specifically, how can you incorporate that “absolute equation” into your own trading?

From here on, we’ll delve into the “concrete formula for lot sizing” to grow assets exponentially, and the “essence of money management that zeros the bankruptcy risk.”
