Simulation Readiness Gate

This is the checkpoint lesson — the gate between learning and risking real money. Everything so far has been preparation: the plan (TF-107), the backtest (TF-108), the psychology (TF-109), the risk rules (TF-106). Before a single real dollar goes in, you must prove — with data, not confidence — that you can trade your plan profitably and follow your rules consistently. That proof happens in simulation: paper trading with fake money in live markets. Most beginners skip this step. Most beginners also lose their accounts. The gate is simple: meet the criteria below, or keep practicing. We will now teach you about paper trading, market replay, the minimum sample size, the compliance score, and how to run an honest go/no-go review.
Paper Trading: Real Markets, Fake Money
Paper trading (also called simulation) means placing trades exactly as you would live — real prices, real spreads, real market hours — but with play money. Most brokers offer a free simulator; paper-trading apps work too. The prices are honest. The fills are realistic enough. The only thing missing is the emotional weight of real dollars, which is both the limitation and the point.
The point is this: simulation tests whether you can follow your plan, not whether you are brave. If you cannot follow your rules with fake money — if you skip the journal, widen stops "just this once," or revenge-trade the simulator — you have learned something priceless: the plan is not the problem. You are not ready. Better to learn that with play money than with rent money.
Trade the simulator exactly as you will trade live. Same setup, same entry trigger, same 1% risk sizing, same daily loss limit, same max trades per day, same journal with screenshots (TF-108). Every shortcut you take in simulation becomes a habit you will carry into real trading. Practice does not make perfect — practice makes permanent. Make sure you are making the right things permanent.
Market Replay: Compressing Years Into Weeks
Waiting for your setup to appear in live markets can make 100 sim trades take months. Market replay solves this: software that replays historical trading days tick by tick, letting you trade them as if live — pausing, placing orders, getting stopped out — at whatever speed you choose. An entire month of your setup's opportunities can be worked through in a weekend.
Use replay to build your sample fast, but keep it honest: no peeking at what comes next, no re-doing a session because you "would have" traded differently. Trade it once, log it once, move on. Replay is also the best place to practice your loss routine and your daily-limit discipline (TF-109) — rehearse the hard moments while they are free.
One caution: replay fills are cleaner than reality. Real markets have slippage and partial fills (TF-105). When you score your replay results, assume slightly worse fills than the software gave you — the same pessimism you applied to backtest costs in TF-108.
The Readiness Criteria: What "Ready" Actually Means
Feelings are not criteria. Here is the gate — all five must be met:
- Minimum 100 simulated trades, taken exactly per your written plan. Fewer proves nothing (TF-108).
- Net profitable after realistic costs — spread, commissions, and assumed slippage subtracted from every trade. Breakeven-or-better is the floor; consistently profitable is the goal.
- Compliance score of 90% or higher — at least 90 of those 100 trades followed every rule: correct setup, correct trigger, correct size, stop honored, targets honored, no rule-breaking entries. (More on scoring below.)
- Daily loss limit respected every single time — not once breached, widened, or "paused for today." One breach resets the count. This rule is the account's life support; there is no partial credit.
- At least one full losing streak survived without breaking rules — a stretch of 5+ consecutive losses (they will come) handled by the book: same size, same plan, no revenge trading. If your sample somehow contains no losing streak, keep trading until it does.
These are minimums, not achievements to rush past. Taking six months to pass the gate is normal and admirable. Blowing through it in three weeks usually means the bar was set too low or scored too generously.

The Compliance Score: Following Rules Is the Skill
The compliance score is the percentage of your trades that followed your plan completely. Score each sim trade honestly: setup matched? Entry trigger exact? Size per the 1% math? Stop placed at invalidation and never moved against you? Exits per the target rules? No impulse entries, no skipped journal entries? One broken rule = one non-compliant trade.
90% is the gate because it reflects reality: nobody is perfect, but professionals are close. Below 90%, your results are measuring your improvisation, not your plan — and improvisation does not scale to real money, where every rule break costs more because emotions are louder.
Score yourself from the journal, not from memory. Memory rounds up. The journal does not. If your honest score comes in at 82%, you do not argue with it — you keep simulating, find which rule keeps breaking, and fix the rule or fix the habit. That is what the gate is for.
The Go/No-Go Review: Deciding Like a Professional
When you believe you meet all five criteria, run a go/no-go review: a formal, written self-assessment. Print your journal summary — total trades, net profit after costs, compliance score, biggest losing streak, any limit breaches (there should be none) — and answer in writing: did I meet every criterion, honestly? If a trading buddy or mentor can review it with you, even better. A witness makes honesty easier.
If go: you do not jump to full size. You start live with the smallest size your broker allows — smaller than the plan's 1% if possible — for at least your first 20–30 real trades. Real money introduces emotions simulation cannot, and you are re-proving compliance under the new weight. Scale up to full 1% risk only after another clean compliance stretch. If no-go: extend simulation. No shame, no rush. Identify the failing criterion, work on exactly that, and re-test. The market will still be there when you are actually ready — and "actually ready" is worth more than every rushed account ever blown.

Key terms
- Simulation (paper trading)
- trading with fake money in real market conditions; proves you can follow your plan before real dollars are risked.
- Market replay
- software that replays historical trading days tick by tick so you can practice and build sample size quickly.
- Readiness gate
- the five-criteria checkpoint (100 trades, net profitable, 90% compliance, limit never breached, losing streak survived) required before live trading.
- Compliance score
- the percentage of trades that followed every plan rule; 90%+ required to pass the gate.
- Go/no-go review
- your formal written self-assessment of the five criteria, ideally with a witness, before going live.
- Small-size start
- beginning live trading below full risk size for 20–30 trades to re-prove compliance under real-money emotions.
What's next
You now know how to earn the right to trade real money — and this school's final stretch is about knowing what you are trading. TF-111 "Futures Foundations" explains futures contracts: what they are, how leverage works inside them, and why beginners start with micro contracts or not at all.
