Strategy & System Design Lesson 1 of 3 11 min read

Building a Complete Trading Strategy

Most retail traders never have a strategy โ€” they have a collection of loosely related habits and reactions. A real strategy is complete, testable, and systematic. It answers every decision before the market forces you to make it under pressure.

What Makes a Strategy "Complete"?

A strategy is complete when it specifies what to do in every possible scenario. Most traders' "strategies" are actually just entry criteria โ€” they know roughly when to buy but have no predefined answer to: how big? Where's the stop? When do you exit profitably? What happens if it doesn't work within X bars? What conditions cause you to skip the trade entirely?

Incomplete strategies are dangerous because they force real-time decisions under emotional pressure. Whenever you don't have a pre-specified answer, your emotional brain fills the gap โ€” and almost always makes the wrong call.

Component Deep Dive: Entry Criteria

Your entry criteria need to be objective โ€” two traders should look at the same chart and agree on whether the criteria are met. Subjective entries ("the setup looked good") are untestable and unmeasurable.

Good entry criteria specify: which timeframe, which indicator values, price action conditions, and volume confirmation. Example: "Enter long when RSI crosses above 30 on the daily chart AND price is above the 50-day EMA AND yesterday's candle closed as a bullish engulfing." That's objective and testable. "Buy when it looks like it's bottoming" is not.

Component Deep Dive: Position Sizing

Position sizing is the most mathematically important component โ€” it determines your survival. The standard formula:

Position Sizing Formula
Position Size = (Account ร— Risk%) รท (Entry โˆ’ Stop) Example: $10,000 account ยท 1% risk ยท Entry $45,000 ยท Stop $43,500 = ($10,000 ร— 0.01) รท ($45,000 โˆ’ $43,500) = $100 รท $1,500 = 0.0067 BTC

This formula ensures you always risk the same percentage regardless of how wide your stop is. A tight stop = larger position. A wide stop = smaller position. The risk in dollar terms remains constant. This is the core of professional risk management.

Component Deep Dive: Stop Loss

Your stop loss should be placed where your trade thesis is genuinely invalidated โ€” not at a round number, not at a level that "feels right," not at the point where you've lost exactly 1%. The stop is the answer to: "At what price does my analysis prove incorrect?"

Common stop placements:

Component Deep Dive: Skip Filters

Skip filters are underrated. Even a great setup has lower-quality instances that should be avoided. Common filters:

Common Skip Filters โ€” When to Ignore a Valid Setup
FilterWhen to SkipWhy
Macro regimeBTC in downtrend > 200 MALong setups have lower edge in bear market macro context
News proximityMajor event < 4h awayNews causes unpredictable spikes that invalidate technical analysis
Low volumeVolume < 50% of 20-day averageLow volume moves are unreliable and more likely to reverse
Already extendedPrice > 2 ATR from key MAExtended price has poor risk/reward for continuation
Personal stateAfter 3 consecutive lossesYour judgment is impaired; half-size or skip until next session
Write It Down Before You Trade ItA strategy only exists on paper if it's written. Write your complete strategy โ€” all five components โ€” in one document before taking your next trade. If you can't write it down in specific terms, you don't have a strategy. You have intentions.
