Trading Calculators

MiniWebtool’s Compound Daily Interest Calculator projects repeated reinvestment at a constant daily gain. Starting capital, active days, and trading days per week generate a growth path; it is a compounding scenario rather than a trading-return forecast.

MiniWebtool’s Implied Volatility Calculator solves for the volatility consistent with an option price under the Black-Scholes model. Iteration details and Greeks help explain the model result; implied volatility is not a forecast of the option’s future return.

MiniWebtool’s Margin Call Calculator models the price threshold at which a leveraged position reaches its maintenance-margin requirement. Position and margin assumptions reveal risk zones; actual broker or exchange liquidation rules may differ.

Explore escalating or reducing stake sizes with MiniWebtool’s Martingale Strategy Calculator. Monte Carlo simulations compare Martingale and Anti-Martingale assumptions, showing capital demands and modeled ruin risk rather than assuring profitable outcomes.

MiniWebtool’s Option Greeks Calculator measures modeled option-price sensitivity through Delta, Gamma, Theta, Vega, and Rho. Charts show how price, time, volatility, and rates affect those sensitivities under the selected pricing assumptions.

Compare technical reference levels in MiniWebtool’s Pivot Point Calculator. High, low, close, and any method-specific inputs produce pivot, support, and resistance levels under Standard, Fibonacci, Woodie, Camarilla, or DeMark rules.

Translate a chosen risk budget into trade quantity using MiniWebtool’s Position Size Calculator. Entry, stop, and account assumptions produce a modeled position size and risk-reward breakdown for long or short trades; gaps and execution costs can change realized losses.

MiniWebtool’s Risk of Ruin Calculator models the chance of reaching a loss threshold from win rate, payoff ratio, and risk per trade. Sensitivity views show how the estimate changes when those assumptions change.
