Drawdown is the fall in your account from its highest point to its lowest point before it recovers. Every trading bot experiences it. Even a profitable bot will spend part of the time below its peak. The question is not how to avoid drawdown completely — that is impossible — but how much is acceptable, and when a drawdown means the strategy is broken and the bot should be stopped.

Many beginners panic at the first 5 percent drawdown and stop a good bot too early. Others ignore a 40 percent drawdown and keep a broken bot running until the account is gone. Both mistakes come from having no plan. This guide gives you numbers to work with and rules to follow before emotions take over.

What counts as an acceptable drawdown?

Acceptable drawdown depends on the strategy, the market, and your own tolerance. As a general guide, a conservative bot trading major pairs with 1 percent risk per trade should rarely exceed 10 to 15 percent maximum drawdown. A moderate bot may reach 15 to 25 percent. Anything above 30 percent is aggressive and hard for most traders to hold through, even if the strategy eventually recovers. Compare the drawdown with the backtest. If the backtest showed a maximum drawdown of 12 percent and the live bot is already down 20 percent, something has changed. Either the market regime is different, the settings were changed, or the backtest was overfitted. A drawdown within the backtested range is normal. A drawdown far beyond it is a warning.

Normal drawdown vs broken strategy

A normal drawdown has a pattern: losses come in small, expected sizes, the bot follows its rules, and the equity curve falls gradually before recovering. A broken strategy looks different. The losses are larger than the backtest predicted, the bot takes trades outside its usual pattern, or the drawdown keeps growing without any recovery for weeks. Other warning signs include a sudden change in win rate, a string of losses much longer than any losing streak in the backtest, and trades that hit stop losses by a wide margin because of slippage or poor fills. Keep a simple record of the bot's maximum drawdown in the backtest, its longest losing streak, and its average loss. When live results break those records by a wide margin, treat it as evidence, not bad luck.

Set your stop rules before you start

Decide your limits in advance, in writing, when you are calm. A practical set of rules looks like this: pause the bot for review if drawdown reaches 15 percent, stop it and re-test if drawdown reaches 20 percent, and never let a single bot risk more than 25 percent of the account. Also set a time rule: if the bot has not made a new equity high in 60 days, review the strategy even if the drawdown is small. A bot that drifts sideways for months is tying up capital that could work elsewhere. Write these rules down and share them with yourself in a note you cannot easily change in the heat of the moment. The point of a pre-set rule is that you follow it when you least want to.

What to check before you stop a bot

Before you stop a bot permanently, run a short diagnostic. First, check whether the market regime changed. A trend-following bot will draw down in a sideways market, and that does not mean it is broken — it may mean it should be paused until a trend returns. Second, check for execution problems: higher fees, worse slippage, or missed trades can turn a profitable strategy unprofitable. Third, check whether you changed any settings recently. A small change to a stop loss or take profit can have a large effect. Fourth, compare the live trades with the backtest trades for the same period. If they match closely, the strategy is behaving as designed and the drawdown is part of its normal pattern. If they do not match, find out why before you restart it.

How to stop a bot safely

Stopping a bot is not just pressing pause. First, check for open positions. Decide in advance whether the bot should close them, leave them with their stop losses in place, or hand them to you for manual management. Leaving open positions without stops is dangerous. Second, cancel any pending orders the bot placed. Third, record the final equity, the maximum drawdown reached, and the reason you stopped it. That record helps you decide later whether to restart the bot, change it, or retire it. If you restart a bot after a pause, restart it small. Do not return to full size immediately. Give it a week or two at reduced size to confirm it is behaving normally again.
