Risk of ruin is the chance an account hits a loss limit before a target. This guide shows the simple even-money formula with hypothetical numbers, the losing streak and drawdown arithmetic, where Kelly sizing goes wrong, and why variable risk or prop drawdown rules need simulation.

Recovering from a loss takes a bigger percentage gain than the loss itself. This guide shows the recovery formula, a full table from 10% to 75% drawdowns, how losing streaks compound at different risk sizes, and how to size a futures account around a worst case you can survive.

A drawdown tells you nothing by itself: it could be normal variance, a market that changed, or your own execution slipping. Here is how to diagnose which, and how to write size-reduction rules in advance so you are not making them while losing.

A daily loss limit works only if it is a number written down before the session and enforced without negotiation. Here is how to size the limit, why stops and flatten orders can still slip past it, how to test enforcement, and what to do after it triggers.

Automation executes whatever risk rules you configure, including bad ones. This guide covers daily loss limits, sizing from tick values, expectancy, drawdown recovery arithmetic and how to test a kill switch, with hypothetical examples.

Account damage usually comes from trade size, not from a single bad entry. This guide shows the contracts formula, worked ES, MES and MNQ examples, a tick value table, and how stop slippage and loss limits change the numbers.

A journal that only lists entry, exit and P&L is a ledger. This guide covers what to log for futures sessions, a short template, the weekly review, the math behind expectancy, and how to keep it up long enough to matter.

A stop only protects you if it is sized, placed and understood correctly. This guide covers fixed, ATR, structure and trailing stops, the contract math for ES and MES, order types and slippage, ATM brackets in NinjaTrader, and how prop firm limits interact with your trade stops.

Risk-reward ratio and win rate only make sense together. This guide shows how to calculate the win rate a given ratio requires, how costs shift it, how to place stops before targets on ES and NQ, and how partial exits change the math.

Scaling up usually breaks accounts because the size changed, not the strategy. Here's how to size from a dollar risk, use micros as a ladder, adjust for wider stops, and set your own scaling checkpoints with real arithmetic.

A 4 point stop means different things on a quiet day and a fast one. Learn how to size futures positions from dollar risk and stop distance, with hypothetical MES and MNQ tables, a simple morning checklist, and a note on drawdown rules.
