Why This Exists
Most traders have no idea what return they actually need to hit their goals — they just start trading and hope. They don't calculate their required win rate. They don't know whether their risk-per-trade can survive a bad month. They find out the hard way, mid-challenge or mid-drawdown, that the numbers were never on their side.
The Trader's Edge Formula was built to remove that guesswork entirely. Every number in your trading plan is calculated, not estimated. Every set of parameters is stress-tested with Monte Carlo simulation before a penny is at risk.
The Five Calculators — One Connected System
1 Zero to a Million Blueprint
Every plan starts here — not with a chart, not with a strategy, with a goal. Enter your starting capital, any monthly additions, your target, and your timeframe. The Blueprint calculates the exact compounded monthly return you need, and gives you an honest verdict on whether that target is realistic.
A 2.5% monthly return sounds modest. Compounded, it's 34.5% a year. £10,000 becomes £13,449 in 12 months from compounding discipline alone — before a single extra pound is added.
2 TEF Simulator
Takes the monthly return from the Blueprint and reverse-engineers everything else: your required win rate, your risk per trade, your reward per trade, and how many trades per month you'd need. This is where "I need 2.5% a month" turns into "I need a 43.2% win rate at 1:1.8 risk:reward, across roughly 40 trades a month" — a plan, not a hope.
3 Position Sizer
Turns your risk percentage into an exact stake or lot size for every single trade — available for both spread betting and lot-size-based platforms. Enter your entry, stop, and target; get your exact risk in pounds, your potential reward, and a live check against your TEF target before you enter.
4 Drawdown Defender
Runs infinite Monte Carlo simulations — randomising the sequence of wins and losses across your exact parameters — to show you what your account actually does under worst-case sequences, not just the average case.
5 Strategy Analyser
Projects your full compounding trajectory using your actual numbers — planned or from your own trading history. Shows you your mathematical edge verdict, and the precise pound value of improving your win rate or risk:reward ratio over 12 months.
How They Connect
Each calculator's output becomes the next one's input automatically. Your required monthly return from the Blueprint flows into the Simulator. Your risk parameters from the Simulator flow into the Position Sizer and the Drawdown Defender. Nothing is retyped, and nothing gets lost between steps — which matters, because the whole point is that these five numbers have to agree with each other for the plan to actually work.
Why I Built It This Way
I spent over two decades as a qualified Independent Financial Adviser and 14+ years actively trading. What genuinely surprised me, after all that time on both sides of the industry, was discovering how rarely traders ever sit down and calculate whether their strategy has a positive mathematical expectancy before risking real capital. They have a strategy. They've backtested it, sometimes. But they've never asked the one question that actually matters: given my win rate, my R:R, and my trade frequency, does this produce a positive expected return — and what does my account look like in the worst realistic sequence?
That missing step is what the Trader's Edge Formula was built to solve.
