Buys keep failing on small marketcap tokens, unsure why

[JR0210]

Hi,

Every time I attempt to buy a small market cap coin I get errors through the pancakeswap router. Wondering if anyone has any ideas as to why this is happening? Pancakeswap gives Fail with error 'PancakeRouter: INSUFFICIENT_OUTPUT_AMOUNT€' Though I'm unsure why, my gas limit is nowhere near used, my slippage is at 47% and I've limited the bot to only buy at max 15% of the token supply if it's low. This also happens in every attempt within a for loop - retry is currently set to 3 max.

I've added the ethers error message and transaction hash etc below

Error: transaction failed (transactionHash="0x9de0323d6f13a1e528ca8e89f4080882554e50413e9975ede3d1456e8e89ed1b", transaction={"nonce":176,"gasPrice":{"type":"BigNumber","hex":"0x0ba43b7400"},"gasLimit":{"type":"BigNumber","hex":"0x0b5d76"},"to":"0x10ED43C718714eb63d5aA57B78B54704E256024E","value":{"type":"BigNumber","hex":"0x00"},"data":"0x5c11d79500000000000000000000000000000000000000000000000000000dbc59ab96ec00000000000000000000000000000000000000000000000000000000003c205900000000000000000000000000000000000000000000000000000000000000a000000000000000000000000066f527de81f3a7883e0910d0c85a785cc3fd44b20000000000000000000000000000000000000000000000000000017a9195dc6b0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000bb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c000000000000000000000000a872960bc3393b2a19aa1e784ab7f385d543ce37","chainId":56,"v":148,"r":"0xdbbd20570d52ac8cda3f531a58777d9cca29162c3cc256685ca67188d66c30fb","s":"0x7789af8db3c51edec64d52dfe55653c104c370e93563b00d3f6ec5cca252a30f","from":"0x66f527de81F3a7883e0910D0C85a785CC3fD44B2","hash":"0x9de0323d6f13a1e528ca8e89f4080882554e50413e9975ede3d1456e8e89ed1b","type":null}, receipt={"to":"0x10ED43C718714eb63d5aA57B78B54704E256024E","from":"0x66f527de81F3a7883e0910D0C85a785CC3fD44B2","contractAddress":null,"transactionIndex":1,"gasUsed":{"type":"BigNumber","hex":"0x031aeb"},"logsBloom":"0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000","blockHash":"0x330e0aea5ac2e96ede62e8a16690401a102de2248fb78062d29fe4d30ef2f61d","transactionHash":"0x9de0323d6f13a1e528ca8e89f4080882554e50413e9975ede3d1456e8e89ed1b","logs":[],"blockNumber":9040739,"confirmations":1,"cumulativeGasUsed":{"type":"BigNumber","hex":"0x068e4b"},"status":0,"byzantium":true}, code=CALL_EXCEPTION, version=providers/5.3.1)

Is it just too slow? Thanks for your help

Hey @JR0210, you may try some debug tools like tenderly to figure out the cause for your tx failure

[JR0210]

Brilliant. cheers for that. It seems as though my calculations for small market cap coins were incorrect 😀
