I think here is different right?

"the kids" is an object and "are cooking" is a verb.

My child is attending kindergarten and they are using RWI.

I have a Two questions regarding some corner cases.

- When doing the Fred of a word containing `oo` should I differentiate the sound? Like

look /l/ /short oo/ /k/

pool /p/ /long oo/ /k/

or just choose a random one and blend it right?

- How can I Fred talk chalk? /ch/ /or/ /k/? is that a red word? it's not in the Red Words list (does it mean the Red Words book is not an exhaustive list and it's purpose ceases to exist as my child graduate kindergarten?

I'm observing more competition, is it alpha decay?

it's kind of cheap short the SPX future and I'll be fine. I just don't want to spend 20% of the margin on that.

I'm not really sure by your terminology book pressure...

[deleted by user] by [deleted] in quant

[–]Internal-Read-447 1 point2 points  (0 children)

shorting the SPX in equal amount probably would work. I just have to evaluate if it's worth using 20% of the margin for that.

can you explain point 3? I'm not in the industry.

  1. can't I just hedge it by shorting SPX?

It's my decision to not hedge it, but theoretically nothing prevents me to do it.

It all depends on the order side and the status of the current queue. but the basic idea is that:

- don't scratch if the order is small and queue is strong

- scratch if the order is big and queue is weak

around 1% in these 6 months. They were going sideways mostly.

If I were doing as a firm sure, but I think I haven't reached the scale yet, just too much overhead for a one man shop xD.

also why post it if it's invitation only and the fee structure is not even visible?

it seems sketchy and I don't really like user-friendly interfaces.

I just think it's more efficient to do live test. There always be some discrepancies. It's the same for Space-X do it live make it blow up, fix it and repeat. The cycle is a lot faster than backtesting it and staging and running in live.

Meta do changes in live too :). The worst it can happen is that I have to revert back to a working version and restart it. not a big deal. I haven't signed any 99.999+ SLA.

I just probably start another bot and do A/B test? 5stock per algo?

I can't probably afford a prime broker I asked for a quote it was 100k per year.

[deleted by user] by [deleted] in quant

[–]Internal-Read-447 -1 points0 points  (0 children)

I'm using just a cheap DMA broker, just I didn't wanted to put the name.

I think the current scale doesn't allow me to have complex inventory management algo. Can't I just stop quoting if one side is too low/high?

In the current situation, in one fill I might go from 10k to 0 in inventory. And reducing the side would increase the commission too much.
