Built a copy trading bot after losing money trying to time markets manually
Been trading on Polymarket for ~6 months. First few months were rough - I'd see a whale enter a position, scramble to copy it, and by the time I placed my order the price already moved.
Got frustrated and built a bot that monitors wallets and copies trades automatically with proportional sizing. Basically:
- Pick traders from leaderboard
- Bot watches their trades 24/7
- When they buy/sell, it mirrors with your balance ratio
Finally profitable after tracking 3-4 consistent traders instead of trying to predict everything myself.
Open sourced it if anyone wants to try: here is github link
What's your approach - manual trading or automation? Curious how others here handle position sizing when copying whales.
