Why Risk Management Is Non-Negotiable
Without risk management, one bad trade can wipe out months of profits. Even the best strategies have losing trades. The goal is not to avoid losses entirely but to keep them small enough that winners outweigh losers.
Automated bots can amplify both gains and losses. A misconfigured bot executing dozens of bad trades can drain your wallet in hours. Proper risk controls prevent catastrophic outcomes.
Position Sizing Rules
The 2% rule: never risk more than 2% of your total bankroll on a single trade. With $1,000, that means $20 maximum per trade. This ensures no single loss significantly impacts your portfolio.
For bots running multiple concurrent positions, set a total exposure limit (e.g., 50% of bankroll deployed at any time). This leaves capital available for new opportunities and buffers against correlated losses.
Stop Losses and Exit Rules
Every position should have a stop loss. On PredictEngine, set the stop loss percentage when configuring your bot. Common stops: 15-25% below entry price.
Time-based exits: if a position has not hit your target within X hours, consider exiting. This frees capital for better opportunities and prevents dead money sitting in stagnant markets.
Drawdown Limits
Set a daily loss limit that pauses all bot trading if reached. Common setting: halt at 5-10% daily drawdown. This prevents spiraling losses during unusual market conditions.
Weekly and monthly limits provide additional protection. If your bot loses 15% in a week, pause and review the strategy before continuing. The market will still be there when you return.
Monitoring and Alerts
PredictEngine sends real-time alerts via Telegram for: bot errors, large losses, stop loss triggers, and unusual market conditions. Enable all notifications when running live bots.
Review bot performance daily. Check win rate, average profit per trade, and drawdown. If metrics deteriorate, pause the bot and investigate before losses compound.

Frequently Asked Questions
What stop loss percentage should I use?
15-25% is common for directional strategies. Tighter stops (10-15%) for higher-conviction trades. Resolution strategies may use tighter stops near expiration.
Should every bot have a stop loss?
Yes, with rare exceptions. Arbitrage bots may not need traditional stop losses since both sides are hedged. All other strategies should have explicit exit rules.
How do I recover from a drawdown?
Reduce position sizes, stick to highest-confidence strategies, and rebuild gradually. Do not increase risk to chase losses.
Can PredictEngine automatically manage risk?
Yes. Configure stop losses, daily limits, and exposure caps in the bot settings. The platform enforces these automatically.
