1
What's an edge?
The mathematical foundation of profitable trading
โ–ผ

An edge is a statistical advantage. In trading, it's a setup where the math favors you. Concretely:

Edge = (Win Rate ร— Average Win) - (Loss Rate ร— Average Loss)

If the result is positive, you have an edge. If negative, you bleed money over time, no matter how lucky you are short-term.

Example: 50% WR, average win $200, average loss $150 โ†’ Edge = (0.5 ร— 200) - (0.5 ร— 150) = +$25 per trade.

Critical: a 60% WR strategy can be losing if average loss > average win. The numbers must add up, not the impression of "winning often".

The 4 pillars of a trading system
If one is missing, you don't have a system โ€” you have a hope
โ–ผ
  1. Entry signal โ€” measurable, repeatable condition
  2. Stop loss โ€” predefined max loss
  3. Take profit โ€” predefined exit target (or trailing logic)
  4. Position sizing โ€” fixed number of contracts or % of account

If you can't explain these 4 elements clearly to a friend, you don't yet have a system. You have an idea.

3
Backtest vs Paper Trading
Two complementary validation steps
โ–ผ

Backtest: simulate your system on historical data. Tells you if there's a statistical edge. Cheap, fast, but you can cheat yourself (lookahead bias, overfit).

Paper trading: execute your system in real time on a simulator. Tells you if YOU can follow the system without emotion. No money risked but the discipline is real.

Tradelo rule: minimum 30 days of paper trading before a real challenge. If you can't follow your system in paper, you won't follow it in live with money on the line.

The 3 most common edges in retail
Where to look for your starting strategy
โ–ผ

Many trading approaches can produce an edge. This course doesn't tell you which one to pick โ€” that's your job as a trader. What matters is:

  • Choosing ONE approach you understand completely and can describe in concrete, measurable rules.
  • Mastering it before adding others โ€” a single well-validated approach beats three half-validated ones.
  • Accepting that no approach is "best" โ€” each works in specific market regimes and fails in others. Rigorous backtesting is how you find out which side you're on.

The honest question to ask yourself: does the approach I trade actually have an edge โ€” or have I just been lucky on a favorable regime? That's what proper measurement answers.

The link with prop firms
Why having a system is CRITICAL for prop firms
โ–ผ

Prop firms have strict drawdown rules. Without a system:

  • You take random trades
  • You hit drawdown after 5 bad days
  • Account blown, fees lost, you start over

With a system, even if you lose, you lose controlled. You know your worst case. You can size accordingly.

The truth: the prop firms ecosystem makes money on traders without systems. They pay $150 challenges, blow up, repay. If you have a real system, you become an asset, not a customer.
