01 · FLAGSHIP TOOL
Stock Scenario Calculator
How to use it: Enter the stock symbol, what one share costs, how many shares you have and how far you think the price may move. The calculator shows the new share price, the new value of all your shares and your possible profit or loss. Example: 20 shares bought at $250 cost $5,000; if the price rises 10% to $275, they become worth $5,500—a $500 gain.
TSLA projected price$275.00
Projected position value$5,500.00
Potential profit$500.00
Original cost: $5,000.00
Bear$225.00-$500.00
Base$250.00$0.00
Bull$275.00$500.00
What this result meansYou invested $5,000.00 at $250.00 per share. In this scenario, the price becomes $275.00 and 20 shares create a hypothetical gain of $500.00. It is an illustration, not a forecast.
02 · TRADE STRUCTURE
Risk / Reward
How to use it: Enter where you plan to buy, where you would exit if wrong, your profit target and your share count. It compares how much you could lose with how much you could gain. Example: 100 shares bought at $50 with a $47 stop risk $300; a $58 target offers $800, or $2.67 of potential reward for every $1 at risk.
Reward-to-risk ratio2.67 : 1
Planned risk$300.00
Potential reward$800.00
What this result meansThe ratio compares the planned upside with the planned downside. It does not measure the probability of either outcome.
03 · RISK CONTROL
Position Size
How to use it: Enter your account value, the percentage you are willing to risk, your planned buy price and your stop price. It estimates how many shares keep the possible loss near your chosen limit. Example: 1% of a $25,000 account is $250; with $3 at risk per share, the estimate is 83 shares.
Estimated position size83 shares
Capital at risk$250.00
Position value$4,150.00
What this result meansThe share estimate keeps the modeled loss near the risk budget if the stop fills as entered. Gaps and slippage can increase the actual loss.
04 · POSITION COST
Average Share Price
How to use it: Add the price and share count for each purchase—up to five entries. It combines them and shows what you paid on average for each share. Example: 10 shares at $100 cost $1,000 and 5 at $80 cost $400; together, 15 shares cost $1,400, so the average is $93.33 per share.
Entry 1
Entry 2
Entry 3
Entry 4
Entry 5
Weighted average price$93.33
Total shares15
Total position cost$1,400.00
What this result meansThe weighted average is the combined cost per share across the entries. It does not reduce the amount of capital exposed or guarantee recovery.
05 · SYSTEM QUALITY
Trade Expectancy
How to use it: Enter how often you win, your average win, your average loss and the number of trades you want to examine. It estimates whether those results make or lose money over many similar trades. Example: Winning 45% at $300 and losing 55% at $150 averages about $52.50 per trade, or $1,050 over 20 trades.
Expectancy per trade$52.50
Expected result over sample$1,050.00
Break-even win rate33.33%
What this result meansExpectancy summarizes the average implied by the win rate and payoff assumptions over many similar trades. A small sample can differ sharply.
