Hardcoded position amount?

[brandonros]

According to the IDL, the buy signature is this:

// buy(amount, maxSolCost)
      const amount = new BN(this.positionAmount)
      const maxSolCost = new BN(this.positionAmount + this.positionAmount * 0.05);
      const transaction = await this.pumpFun.anchorProgram.methods
        .buy(amount, maxSolCost)

I could be wrong but I think when a token is launched, its supply is kind of "unique". Certain amount of decimals, etc.

I would have thought you needed to do math to figure out for example how many tokens 0.1 SOL (after slippage? before slippage?) would get you

You're right, this ends up being a different amount of SOL every time and can buy into a large position if too much time has passed. I'm willing to look into this or accept PR's, let's keep this open for now.
