What's New
StubBot has been rebuilt from the ground up for 2026 — faster, smarter, and autonomous.
Seamless Auto-Updates New
StubBot checks for updates on launch and automatically patches itself via the cloud. You will never have to manually download and extract zip files again.
Runs in The Background New
Runs autonomously in the background without any keyboard or mouse takeover. Minimize the window and use your PC or laptop normally while it works.
Parallel Buy & Sell Orders New
Additional optimizations such as sell orders are now able to be placed during the buy order phase, cutting update cycles and keeping your listings competitive around the clock.
Direct Price Reading New
Stub prices are read directly from the app's UI, replacing unreliable OCR. Prices are captured accurately.
Rock-Solid 24/7 Reliability New
Rebuilt with robust error handling and smarter app state tracking. Recovers automatically from app hangs, network hiccups, and UI inconsistencies — designed to run for days unattended.
MLB Cards and Sponsorships AddedNew
Diamond Equipment, MLB Live Series cards, and Sponsorships can now be flipped by the bot.
Quick SetupNew
Automate the installation processes with a new script. Designed to get you up and running faster.
Humanized Sleep Schedules New
Set active hours for the bot to run and sleep (e.g., 7 AM to 10 PM), plus randomized pauses between market cycles to realistically mimic human behavior. You can also cap your max orders per day for safety purposes. It also intelligently cleans up remaining buy orders and loops through revising sell orders 30 minutes before the active hour ends.
Sell Duplicates Utility New
A new dedicated mode to automatically scan your inventory and sell off all duplicate cards while keeping exactly one copy for your collection.
Prerequisites
System Requirements
- Windows 10/11 64-bit PC or Laptop

- The bot buys Diamond Equipment saved to your favorites, and MLB Live Series cards saved to your Watchlist.
- Tap the heart icon on each item to add to your watchlist or favorites.
- Any items in your inventory will automatically be listed for sale.
Emulator Settings
Configure the following in your emulator's settings for best compatibility:
Graphics & Display
- Graphics → Vulkan mode
- Display → Tablet mode, 1920×1080, DPI 280 (other resolutions untested)
- Optional: Enable "Dynamically adjust frame rate" (15 Frame) — saves energy when running in background

Core Features
StubBot intelligently manages your MLB The Show market activities:
- Places buy orders exclusively for your favorited/watchlist items.
- Automatically reads stub prices and calculates the profit gap to make smart buy order decisions.
- Detects when your buy orders are low and strategically places more.
- Pauses placing bids when your stub balance is depleted.
- Actively revises existing buy and sell orders to stay competitive.
- Checks your inventory for newly acquired cards and places sell orders for each.
- Designed to loop continuously until you manually stop it or specific criteria is reached (capped max orders, active hours).
Setup & Configuration
First Launch
- 1Double-click
StubBot.exeto launch. - 2Create a username and password, then paste your license key to register.
- 3Credentials are securely saved to your Windows Credential Manager for automatic login on future launches.
- 4Press F10 at any time to pause or resume the bot.
Configuration Panel
Adjust your bot's behavior directly from the built-in Configuration Panel. Toggle Market preferences (Equipment, Sponsorships, MLB Cards), set custom profit margins, and manage your automated sleep schedules without touching a single line of code:
- Market Toggles — Enable/disable Equipment, Sponsorships, and MLB Cards.
- Economics — Set custom profit margins for each specific item type.
- Limits — Control inventory saturation with Max Buy Orders Per Item.
- Timers & Humanization — Enable active hours for automated bot bedtimes and randomized sleep limits.
- System — Select your target console (PS, XBOX, SWITCH) and emulator ADB port.
Bot Loop Strategy
Starts at your home screen, runs these steps in order, then repeats:
- 1Submit Buy Orders — Scrolls through favorited items and places buy orders.
- 2Revise Buy Orders — Reviews existing bids and updates any that are no longer competitive.
- 3Check Inventory — Scans for newly acquired cards/equipment and lists them for sale.
- 4Revise Sell Orders — Reviews existing listings and undercuts the market where needed.
- 5Sleep & Repeat — Waits for the configured sleep duration, then loops back to step 1.
Advanced Execution Modes
Use the Execution Mode dropdown in the app to isolate specific tasks. Run utilities like 'Sell Duplicates', calculate 'Lifetime Earnings', or lock the bot exclusively into 'Revise Sell Orders' with a single click.
- Standard Master Loop — Runs the standard 1 through 4 loop.
- Start at Step 1-4 — Jump directly to a specific step in the loop upon launch.
Isolated Loops & Utilities:
- Isolated: Revise Buy Orders Only — Locks the bot to only revise active buy orders continuously.
- Isolated: Revise Sell Orders Only — Locks the bot to only revise active sell orders continuously.
- Utility: Sell Duplicates — Run once to scan inventory, sell all dupes, and keep 1 copy.
Do's & Don'ts
Do 👍
- Update orders manually through the companion app, website, or in-game as you normally would.
- Place your own buy/sell orders manually if desired. The bot will work alongside your orders.
Don't 👎
- Have active buy/sell orders for large quantities of unsupported item types (like Unlockables or Stadiums). This can confuse the bot, causing it to reload repeatedly until those orders are cleared.
Known Limitations
- Companion App Stability: The bot's performance can be affected by SDS server stability. If the app is unresponsive, the bot will continuously refresh until it loads properly. Downtimes are common around 3:00 PM Eastern (new card releases) and Fridays at 3:00 PM Eastern (roster updates).
- Sliding Mitts: Currently, sliding mitts cannot be found in the My Inventory tab by the bot due to not having an inventory slot in the app.
- Bats Ignored: The bot is designed to ignore bat items and will not flip them.
