The spot and contract price differences on lighter are still quite frequent.
Previously, I only did arbitrage between contracts.
So I’ve now added spot and contract arbitrage.
You need to prepare ETH and USDC in your account in advance.
This way, you can do two-way arbitrage.
The downside is that the capital efficiency isn’t great. But the goal is just to farm points.
If efficiency is low, so be it. I don’t expect to make much money from this anyway.
I’m still running grid strategies as usual, and with arbitrage added, this is the approach for now.
The script I previously open-sourced was only

If you want to run a lighter spot grid, here’s my previous script.
It just needs a slight modification:
Upgrade to the latest version of the SDK. Then change the signing method and use the 2048 market ID, and that’s it.
The script’s running logic itself doesn’t need to be changed. Just modify the adapter. Since spot has just launched, the points should be a bit more (just a guess).
(If you want to run a spot short grid, just borrow ETH and place sell orders.)

The price-performance ratio of the Mac Mini M2 Max 32GB feels quite good, around 8000 yuan.
The price is equal to 2.5 units of calcium board m4
Multi-instance background running and script execution are very suitable.
It feels stronger than the m4 version; I think the cover always falls a bit short.
I bought everything from m1 to m4. It also includes the max version. 😂

The multi-exchange model is almost ready.
Three order types have been successfully executed.
Start testing long-term stability and optimizing details.

For some friends who are just starting to code, I recommend some interesting things.
The most feared thing when mining is losing the internet or power. If you, like me, prefer not to use a server and like to mine locally,
(I'm not good at inputting commands, so I'm not used to the server, but I can use it)
You can take a look at this UPS power supply. It costs a few thousand yuan and can withstand a power outage for 8-24 hours depending on how many batteries you buy. For network issues, just buy a data card as a backup.

With a try-it-out attitude, I clicked on apply for ambassador. It's so easy to get approved.
Can you approve my API application? Bro.
@edgeX_exchange

Why can't I link the Wallet? @edgeX_exchange

Is it appropriate to charge the fees like this? @edgeX_exchange
Are you treating yourself as a bank or treating yourself as...
By percentage? I'm also impressed.
Even if you have ten thousand reasons, you can't do it by percentage.

Today I just saw that @edgeX_exchange's API requires a volume of 1m to apply. Although this condition isn't very difficult, I don't want to lose on transaction fees to quickly hit 1m.
If there are any friends willing to help provide an API testing script, please contact me.
Currently, all theoretical algorithm logic and the entire running link have been completed. Only real market testing is left.
For now, let's first do practical tests with 3 exchanges before adding other exchanges.
A placeholder has been written in advance to expand the exchange.
