Trading Tools Comparison
ApexVol also publishes a free options profit calculator, but it sits in front of a paid, live-data analytics platform. Here's how a free calculator library and a subscription options terminal actually compare.
TradingHabits and ApexVol solve different problems. ApexVol is an options analytics platform built around live institutional-grade data across 5,500+ tickers: real-time option chains, a Greeks heatmap, dealer gamma exposure (GEX) and vanna/charm positioning, a volatility surface and IV-rank lookup, an options flow and screener, and a strategy simulator, all delivered through a single "Terminal" view where more modules become available at each paid tier. TradingHabits is a free library of narrow, single-purpose calculators: type in your own numbers and get one answer, like a Greek, a position size, or a margin requirement, with no subscription, no live data feed, and no account behind it.
Worth noting directly: ApexVol's own options profit calculator is free with no signup for a set of 13 popular tickers (AAPL, TSLA, SPY, NVDA and others), and it's a capable tool on its own, live-updating P&L, breakeven, and all five Greeks (Delta, Gamma, Theta, Vega, Rho) pulled from real institutional pricing rather than a manual Black-Scholes entry. But it's explicitly a lead-in to the paid platform: any ticker outside that free list, the multi-leg strategy builder, real implied volatility data, and the rest of the Terminal's 51 modules require a 7-day free trial (card required) and then a Basic, Premium, or Pro subscription.
| TradingHabits | ApexVol | |
|---|---|---|
| Price | Free, all calculators, no tier | Basic $55/month, Premium $95/month (most popular), Pro $195/month, quarterly billing at roughly 18% off; a free tier and a 7-day free trial (card required) exist alongside the paid tiers |
| Signup required | No account, no email, no login, for any calculator | No signup for the free calculator on 13 listed tickers; a free account or a card-backed trial is required for every other ticker and for GEX, flow, screener, and volatility-surface modules |
| What it's for | Answering a specific pre-trade math question: position size, risk/reward, pip value, options Greeks, drawdown, futures margin, and similar | Running live options analytics on real market data: option chains, Greeks, dealer positioning, volatility surfaces, and multi-leg strategy simulation across thousands of tickers |
| Core product | None. This is a calculator library, not a data or analytics platform | The ApexVol Terminal: a single live screen combining option chains, Greeks, dealer GEX, IV analytics, flow, and a strategy simulator, with more of its 51 modules available at higher tiers |
| Free calculators | Entire site: 300+ calculators across stocks, options, futures, forex, and crypto | One free options profit calculator (13 tickers, live data, all five Greeks), plus separate free calculator pages for IV rank, IV crush, straddles, covered calls, and several other single-purpose strategy calculators |
| Best for | A quick, one-off calculation you want an answer to right now, without creating an account or paying for a subscription | Traders who want live option chains, real Greeks, and dealer-positioning data as an ongoing part of an active options-trading process |
These aren't mutually exclusive. A trader could use ApexVol's free calculator, or a paid tier's live chain and Greeks, to shape a view on a specific ticker, then check the resulting position size, margin requirement, or risk/reward math with a TradingHabits calculator before placing the trade. The calculators here don't store anything or require an account precisely so they can sit in that quick, pre-trade moment without adding another login to a decision that just needs a number.
