Risk management tools
Free, private, in-browser risk calculators — size a position, set your risk per trade, estimate your risk of ruin, find the Kelly fraction, weigh reward against risk, measure drawdown and its recovery, and check your total portfolio heat. Everything runs in your browser; nothing is sent to any server.
Risk management tools: a set of client-side calculators to convert a stop and a risk budget into a position size, express risk per trade in rupees and percent, estimate the probability of ruin, compute the growth-optimal (and safer half-) Kelly fraction, turn an entry, stop and target into a reward-to-risk ratio and breakeven win rate, measure the worst drawdown of an equity series and the gain needed to recover it, and total your open risk as portfolio heat. All results are illustrative and exclude real costs unless stated.
Position Size Calculator
ToolTurn a fixed-fractional risk rule into a concrete number of lots, so a stopped-out trade costs only a small, survivable slice of your capit…
Risk Per Trade Calculator
ToolCheck the exact rupee and percentage of capital a planned trade puts at risk if the stop-loss is hit, before you place it.
Risk of Ruin Calculator
ToolEstimate the probability that a run of trades drives your account down to a chosen ruin threshold, given your win rate, payoff and per-trad…
Kelly Criterion Calculator
ToolFind the growth-optimal Kelly fraction and the safer half-Kelly to stake, from a win probability and payoff ratio — with the usual warnings.
Reward-to-Risk Calculator
ToolTurn an entry, stop and target into a reward-to-risk ratio and the breakeven win rate the trade demands.
Drawdown Calculator
ToolPaste an equity series to find the largest peak-to-trough fall and the recovery gain that fall demands.
Portfolio Heat Calculator
ToolAdd up the risk on every open position to see your total open risk as a percentage of capital — the exposure a single bad session could rem…
