If you trade on Polymarket and want real automation (not gambling), this is the bot you’ve been waiting for.

Polymarket Trading Ping‑Pong Bot (also known as Polymarket Copy Trading Bot – Smart SL/TP, Automated Profit & Risk Management) is a production‑ready automated copy trading system built for serious traders who want control, speed, and protection.

This project is my improved and upgraded version of an open‑source Polymarket bot. I took the original concept, rebuilt the logic, and added professional‑grade risk and profit systems that real traders need.

Below is a deep breakdown of what this bot actually does, based on the real code and architecture — not marketing fluff.

What Is the Polymarket Trading Ping‑Pong Bot?

The bot is an automated trading engine that:

Copies top Polymarket traders in real time
Calculates your trade size based on your balance and risk strategy
Executes trades directly on Polymarket’s CLOB
Manages open positions with smart take‑profit and stop‑loss logic
Tracks your activity and positions with full transparency

This is a local, self‑hosted bot. It runs on your machine or server. Your private key never leaves your device. You stay in full control of your wallet and funds.

Why This Bot Is Different From Basic Copy Trading Bots?

Most copy bots just mirror trades. This one is designed to protect your capital and lock profits with smart automation.

Here are the real systems inside the project:

1) Real Copy Trading Engine (Not a Fake “Signal” Bot)

The bot monitors selected trader wallets and copies their trades using the Polymarket Data API and CLOB order execution:

Monitors trade activity continuously (default 1 second interval)
Detects new trades and stores them in MongoDB
Scales trades based on your balance and strategy
Executes matching orders using Polymarket’s order book

This is real execution, not delayed signals.

2) Smart Position Sizing (3 Strategies + Tiered Multipliers)

You can choose how the bot sizes your trades:

Percentage strategy (copy a % of trader’s order size)
Fixed size strategy (copy a fixed dollar amount)
Adaptive strategy (ptercentage scales by order size)

Plus: Tiered multipliers let you scale differently based on trade size. This is powerful for controlling risk when traders place huge orders.

You also get safety controls:

Min and max order size
Max position size
Max daily volume (optional)

3) Price & Odds Protection (Avoid Bad Fills)

The bot won’t blindly buy or sell. It checks the order book and applies guardrails:

Slippage guard: skips trades if price moved too far
Min / Max odds: avoids extreme prices (like 0.01 or 0.02 or 0.99)
Minimum order size: obeys Polymarket’s $1 rule

This keeps you out of risky or low‑liquidity fills.

4) Ping‑Pong Strategy: Smart Take‑Profit + Smart Stop‑Loss

This is one of the biggest upgrades in this project.

The Ping‑Pong engine is a dedicated TP/SL manager that runs on your own positions and uses real order‑book PnL (best bid vs. your average price).

It supports:

Custom TP Min / TP Max Sell part at a first target, then sell more at a higher target.
Runner Mode (Partial Profit) Keep a portion of the position open for bigger wins.
TP “No‑Loss Guard” Before selling, it checks the best bid again. If the price is not truly profitable, it won’t sell. This prevents “green but sold red”.
Smart SL Delay Instead of panic selling, it delays stop‑loss and looks for bounce exits. It will attempt a smart exit only if the bid price is at breakeven or better.
Cooldowns Prevents spam selling and over‑trading during volatile moments.

This is real risk management, not just a simple “sell when red”.

5) Real‑Time Order Book PnL (Not Fake API Values)

PnL is calculated using live order book best bids, not delayed API prices. That means TP/SL decisions are based on real liquidity.

6) Trade Aggregation (Solves Small‑Trade Issues)

Polymarket has a minimum $1 order size.This bot can aggregate small trader orders into a single larger order, so you don’t miss opportunities when copied trades are too small.

7) Emergency Exit Tools (Urgent Sell Modes)

This project includes urgent sell tools for critical market conditions:

Normal Panic Sell (sell at any price)
Safe Exit Mode (only if breakeven or small profit)
Strict Profit Exit (only if profit exceeds your custom target)

This is ideal for “close everything now” situations.

8) Full Transparency + Local Control

Everything runs locally:

Your wallet keys remain private
All trades are logged and stored in MongoDB
You can inspect and customise every part of the code

No third‑party servers, no Telegram bots, no hidden logic.

Tech Stack (Credibility Matters)
