Read full descriptionHide full description
Know if your FTMO setup can pass before you pay another $540 for a challenge. RangeSight runs 10,000 simulated FTMO challenges against your exact strategy and FTMO's real drawdown, daily loss, and profit target rules. It gives you one number you can act on: your pass probability. How it works: 1. Enter your strategy's numbers (win rate, average win and loss, trades per day). 2. Choose the FTMO challenge size and rule set. 3. RangeSight runs 10,000 Monte Carlo simulations and shows your pass probability, your likely maximum drawdown, and where most attempts fail. Why it matters: A prop-firm challenge fee is real money. Before you risk it, see the odds your strategy actually clears the rules, not a guess, a simulated distribution across thousands of runs. One purchase. No subscription. FOUNDER LIFETIME: $29.99 one-time. First 1,000 buyers only. After that, retail is $99.99 lifetime still less than one failed FTMO 100K retry. — WHAT YOU GET — - Pass Probability "31% of simulated candidates pass with your current risk." One number. Act on it. - Real failure modes drawdown breach, daily-loss cap hit, or ran out of days. Ranked, so you know which rule is the actual problem. - Suggested risk reduction when your odds are marginal, RangeSight tells you the exact risk-per-trade that puts you in the passing band. - 10,000 Monte Carlo paths per simulation fat-tail aware, vol-adjusted, absorbing-barrier modeled. - Strategy Library save your setups, compare them, re-run after you tweak. - Scalper, day trader, and swing trader presets. - Saturday Weekend Digest weekly review of which strategies stayed in the passing band. — BUILT FOR FTMO. WORKS FOR 23 OTHER FIRMS. — RangeSight is purpose-built for FTMO traders, with FTMO's actual rule structure modeled correctly (10% max drawdown, 5% daily loss, 10% profit target, two-phase evaluation). The same engine supports 23 other prop firms: Apex Trader Funding, Topstep, MyFundedFX, FundedNext, E8 Markets, The5%ers, Goat Funded Trader, and more each with their own drawdown structure (static, trailing, or trailing end-of-day). — WHY THIS EXISTS — FTMO challenges cost $155 (10K) to $1,080 (200K). The 100K eval is $540. Most failed attempts are not bad luck they're the same trader, the same setup, breaking the same rule on the same trade type. RangeSight lets you watch 10,000 versions of your strategy run through your FTMO evaluation BEFORE you pay for another retry. The simulation is honest. If your strategy genuinely passes, RangeSight shows 80%+ pass rates and tells you. If it doesn't, RangeSight shows you the rule you're going to fail. No artificial fear-tuning. No upsell-driven results. Note: simulation models Phase 1 only. Phase 2 has a 5% target instead of 10% your real pass odds are typically 10–20% lower than the simulation shows. Use the result as a floor, not a guarantee. — PRICING — Founder Lifetime: $29.99 one-time first 1,000 buyers only, 60 days, no renewal, no auto-charge, ever. Retail Lifetime: $99.99 one-time after the founder window closes. No monthly subscriptions. No yearly subscriptions. Buy it once. Not affiliated with FTMO, Apex Trader Funding, Topstep, or any prop firm. Educational simulation only. Verify current rules with your firm before trading. RangeSight does not broker funding. Pass probability is a simulation output, not a guarantee.

Verdict
The clearest difference is in-app purchases: Leftly at none against RangeSight Studios's 4. RangeSight Studios's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.1). On price, update cadence and device support there is nothing between them.
