Kill switch and flatten controls for Topstep-compatible bots

When this topic matters

• You are about to connect anything that can place live orders
• Your strategy restart behavior is undefined
• You have never practiced flatten while calm
• You assume “I’ll just close the app” is a procedure
• You are promoting a bot into a stage where mistakes are expensive

Define the verbs before you need them

Write what each action means in your workflow:

• Stop — halt new strategy decisions / new entries
• Flatten — close open positions according to your procedure
• Disconnect — break the live routing path safely
• Kill switch — highest-urgency path to cease automated activity
• Diagnostics — inspect connection state, bots, logs, limits

Exact UI labels can vary by product version. Confirm them in your installed build; this guide does not prescribe a click-path. The point is that these jobs exist and stay reachable.

Why prop accounts need this more, not less

Automation is fast. A stuck working order, a bad regime, or a lost connection can turn into a platform-rule problem quickly. Topstep publishes prohibited-conduct and responsible-trading guidance — automation does not create an exemption. Emergency controls are how you keep a bad minute from becoming a career story.

Speed without brakes is not sophistication.

Practice on a quiet day

Do not discover the flatten button during a margin-of-error moment.

1. Confirm you can see bot state and connection state
2. Confirm stop prevents new entries
3. Confirm flatten behavior matches your written plan
4. Confirm restart / reconnect does not surprise you with unmanaged risk
5. Confirm diagnostics are readable enough to be useful under stress

Botfolio messaging also references lifecycle checks — checking running bots, open positions, and pending protective orders before restart-style actions. Treat restarts as deliberate.

Pair emergency controls with stand-downs

A kill switch is the fire extinguisher. A stand-down rule is the smoke detector. You want both: automatic refusal to continue a ruined day, plus human-triggered emergency actions.

If you only have emergency controls, every bad day becomes a manual drama. If you only have stand-downs, surprises still need a human path.

Activation and “new starts blocked”

Homepage copy notes that if activation needs attention, new starts can be blocked while stop / disconnect / kill / flatten remain available. That is a safety posture: do not confuse “cannot start new bots” with “cannot exit risk.”

If you are in an activation edge case, prioritize exit clarity and contact support@getbotfolio.com for checkout/activation issues when relevant.

Restart hygiene (the boring killer)

Classic failure mode:

1. Bot has open risk and working protective orders
2. Something flakes
3. Operator restarts casually
4. State assumptions drift
5. Duplicate exits / missing exits / surprise entries enter the chat

Prefer a checklist:

• What bots are running?
• What positions are open?
• What protective orders are pending?
• What is connection state?
• What am I about to start, and why?

Hypothetical drill script (not a live-trading tip sheet)

T0: Flat, connected, strategy idle. Open command center. Read diagnostics.

T1: Arm stop. Confirm no new entries if you nudge conditions in a safe test context.

T2: In a controlled supervised scenario appropriate to your environment, practice flatten and narrate aloud what you expect to happen.

T3: Disconnect intentionally. Confirm you understand reconnect checks.

T4: Write notes on anything confusing. Confusing controls under calm become unusable under panic.

Adjust this drill to your access and product version. Do not invent simulated environments Botfolio has not documented for you.

Common failure modes

1. Emergency controls exist but were never practiced
2. Stop and flatten are conflated mentally
3. Kill switch used as a substitute for missing stand-downs every day
4. Restart without position/protective-order inspection
5. Assuming closing the laptop equals a clean trading shutdown

Rule / ops design checklist

• Written definition for stop / flatten / disconnect / kill
• Diagnostics location known cold
• Drill completed while calm
• Restart checklist written
• Stand-downs configured so emergencies are not your only brake
• Support contact known for activation issues
• Official Topstep rules reviewed for conduct expectations around automated trading

What Botfolio does / does not claim

Does

• Market supervised automation with stop, flatten, disconnect, kill switch, diagnostics
• Describe lifecycle checks around bots, positions, protective orders before restart-style actions
• Keep exit controls available even when new starts may be blocked during activation attention

Does not

• Guarantee limited losses
• Claim unattended autopilot safety
• Replace platform risk controls or official rule compliance
• Promise any trade outcome

Incident playbooks worth writing before you need them

Playbook: unexpected open position

1. Stop new entries
2. Read diagnostics / connection state
3. Identify protective orders
4. Flatten per written policy if required
5. Disconnect if routing is untrusted
6. Journal what the bot thought it was doing

Playbook: connection flap mid-trade

1. Do not spam restart
2. Inspect positions and pending protective orders
3. Prefer controlled reconnect after state is understood
4. Only then consider whether strategy may resume

Playbook: strategy behavior looks “off”

1. Stop
2. Capture logs / notes
3. Demote to replay review
4. Do not “fix live” with bigger size

These playbooks are educational templates. Adapt them to your product version and platform rules.

Field notes from supervised operators (composite, not testimonials)

These are composite lessons distilled from common prop-automation failure patterns — not customer quotes, not verified Botfolio case studies, and not performance claims:

• The bot that lacked a day-level stand-down did not fail dramatically; it failed by a thousand cuts.
• The operator who skipped flatten drills discovered that “I know where the button is” is not the same as using it under adrenaline.
• The strategy that looked robust until session windows were segmented was actually a one-hour idea wearing an all-day costume.
• The stage transition that reused old size settings turned a previously tolerable loser into an outsized budget event.

Use them as warning signs in your own review meetings.

Putting the education into a Botfolio-shaped operating cadence

Even when this article is mostly about trading process, the practical cadence still maps to Botfolio’s verified loop:

1. Encode the rule changes you just designed.
2. Replay before granting live-order privileges.
3. Promote only with account/sizing/risk settings explicit.
4. Supervise from the local command center with emergency actions reachable.
5. Demote back to replay when live behavior disagrees with the story you told yourself.

That cadence will not make a weak edge strong. It will keep weak process from impersonating a strategy.

Compliance reminder you should re-read often

Automation does not create a special exemption lane. If Topstep classifies a behavior as prohibited conduct or a prohibited strategy, doing it via software is still doing it — usually faster. Keep official help pages in your weekly ritual, especially around API access, prohibited conduct, prohibited strategies, and responsible trading. This site’s older checklist post remains useful as a prompt, not as a substitute for primary sources: Topstep automated trading rules checklist.

Quick takeaways

• No. Market risk remains. Controls help you intervene and enforce process; they do not guarantee outcomes.
• Automatic flatten is a design choice with tradeoffs.
• No. Botfolio is marketed for supervised automation with human override present.
• In your written procedure, stop often means “halt new activity,” while kill is the highest-urgency cease path.
