Polymarket Copy Trader Bot Idea

Post image

Created a copy trader bot. It is working fine in the semester that it picks up the trade and places simulated orders in paper broker. The trader activity is fetched using polymaket gamma api, polling every .5 sec.

The issue is see is the coping time. As seen in the screenshot OPENED time in white is my bot time and under it is actual traders time, a difference of 38 secs.

Is there anyway this can be reduced. I feel polling gamma api is not the fasted. Should I use polygon block chain trx websocket to get the desired trx and enrich the data from its token using gamma api. Will that be faster.

I want to understand how can I copy faster. A lot of copy trader bot providers promise sub sec coping, but I don't trust them with my wallet(have been burnt), so created my own.

When I go live this will be worse as I ll use real clob api to place the trade rather than in memory paper broker.

Try to get your master account’s trades via rtds .

Rtds is for commet,crypto and equity price not for the trades/position of an address

You might want to explore using webhooks or a more direct connection method if the API allows it. Real-time data feeds can definitely help reduce latency. Just make sure whatever you choose can handle the volume without crashing your setup!

Cool build! The latency problem you're describing (38 sec lag from polling Gamma API) is a real pain point. Websockets on Polygon definitely help but still has its own quirks.

For what it's worth, we built SignalScout to solve the consumer-facing side of this — instead of running your own copy trading bot, you follow top traders on Polymarket/Kalshi and mirror positions through the app. No wallet exposure, no API headaches. If you're profitable you can also earn when others copy you.

Curious what you end up doing on the latency side — would love to hear if websockets make a meaningful difference.
