bancor
@hama, yes, you can calculate price manually using bancor protocol (I noted it above), but this is still frustrating. Why can't you know the price before you buy or sell? Why should you guess price every time you wanna buy it? Why no price tags?
you can use the following method:
run cleos get table eosio eosio rammarket
you'll get something like:
"rows": [{
"supply": "10000000000.0000 RAMCORE",
"base": {
"balance": "14974544245 RAM",
"weight": "0.50000000000000000"
},
"quote": {
"balance": "4589161.3885 EOS",
"weight": "0.50000000000000000"
}
}
]
then 4589161.3885 / 14974544245 x 1024 = 0.3138 is the RAM price per KB.
This helped me, keeping in mind fee of buyram action (0.5%): https://github.com/EOSIO/eos/blob/369c7e31e17630e1327a48869b832635352a27f4/contracts/eosio.system/delegate_bandwidth.cpp#L111 With this in mind I get accurate results! Thanks a lot!
Still, do you plan to implement ram price endpoint?
Yes, we'll implement it in the future.
For people implementing this in the future here's some roughed-out sample code: https://runkit.com/slipo/5b5a37b59fefb60012b18a90
Plus the related endpoint: https://runkit.io/slipo/5b5a37b59fefb60012b18a90/branches/master
@taokayan why would you close this if it isn’t resolved? Maybe you should close this when you implement it?
It would be nice to have RAM price data accessible as API endpoint (or in
get_info
endpoint response for example). Now you know the ram price only after you have bought/sold RAM (or you can somehow calculate price based on bancor protocol or something). This is very unpleasant.
