How to calculate 100 vote worth

In this tutorial I will show you how to calculate the 100% vote worth at a given moment. This can vary very quickly depending of available steem, sbd and the market price.

Prerequisites

• Get account info
  steem.api.getAccounts Retrieves the related data for the account being query, use the position 0 as this returns an array of objects, you can also query multiple accounts at the same time like ['acc1','acc2'] and so on. Make sure to use the correct data to the account you want to calculate vote worth.
• Get global info
  steem.api.getDynamicGlobalProperties retrieves data regarding the total vesting fund and vesting shares, required for steem formatter and also for vote calculation.
• Get reward funds
  steem.api.getRewardFund the available data for the current rewards pool
• Get current median history price
  steem.api.getCurrentMedianHistoryPrice the historical average/value of the STEEM and SBD rate.

Process

Once you have the account information and also the global information, calculated the overall vests for the account, make sure to take out the delegated ones. Calculate the current voting power calculating the difference from the last vote performed with the current time. Use steem.formatter.vestToSteem to get the human readable for the steem power.

var steem = require('steem'),
wait = require('wait.for');
var vote = 0;
var sp = 0;
var vp = 0;
steem.config.set('websocket','wss://steemd.steemitdev.com');
wait.launchFiber(function() {
  var globalData = wait.for(
    steem.api.getDynamicGlobalProperties
  );
  var accounts = wait.for(
    steem.api.getAccounts,
    ['tuanis']
  );
  var data = wait.for(
    steem.api.getRewardFund,
    'post'
  );

  var vestingSharesParts = accounts[0].vesting_shares.split(' ');
  var receivedSharesParts = accounts[0].received_vesting_shares.split(' ');
  var delegatedSharesParts = accounts[0].delegated_vesting_shares.split(' ');

  var vests = (
      parseFloat(vestingSharesParts) + 
      parseFloat(receivedSharesParts)
    ) - (parseFloat(delegatedSharesParts));
  console.log('Vests: ' + vests);
  var then = new Date(accounts[0].last_vote_time);
  var now = new Date();
  var seconds_since_last_vote = (now - then) / 1000;
  vp = (seconds_since_last_vote * 10000 / 86400 / 5) + 
    accounts[0].voting_power;
  console.log('Voting power is: ' + vp);

  sp = steem.formatter.vestToSteem(
    vests,
    parseFloat(globalData.total_vesting_shares),
    parseFloat(globalData.total_vesting_fund_steem) 
  );
  console.log('Steem power is: ' + sp);
  // Saving the data
  var m = parseInt(100 * vp * (100 * 100) / 10000);
  m = parseInt((m + 49) / 50);
  var i = parseFloat(data.reward_balance.replace(' STEEM', '')) /
    parseFloat(data.recent_claims);
  var sbd_base = wait.for(
    steem.api.getCurrentMedianHistoryPrice
  );
  var o = parseFloat(sbd_base.base.replace(' SBD', '')) /
    parseFloat(sbd_base.quote.replace(' STEEM', ''));
  var a = globalData.total_vesting_fund_steem.replace(' STEEM', '') /
    globalData.total_vesting_shares.replace(' VESTS', '');
  var r = sp / a;
  vote = parseInt(r * m * 100) * i * o;
  vote = vote /100;

  console.log('Vote value: ' + vote.toFixed(2));
  process.exit();
});
