I want to set watch for my public address. So i can get all transaction for that address.

My code is:

var filter = web3.eth.filter({ address: ["0x2A7146700BCe4A574eE36D5e9cd6CF7d8871aEB6"] });
    filter.watch(function (error, result) {

When any transaction occur from ethereum blockchain, i need to call my event.

No, currently there's no event triggered when the balance of an address has been modified.

Your account balance can change without a transaction, if your address is used in the miner field of a block or uncle it will be credited with the reward, but no transaction is involved. The balance can be credited in an "internal" transaction.

The closest thing you can do is setup a block filter event and monitor for each new block if your balance has changed.

const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

const address = "0x....";

let balance = web3.eth.getBalance(address);

const filter = web3.eth.filter('latest');
filter.watch((err, res) => {
  if (err) {
    console.log(`Watch error: ${err}`);
  } else {
    // Update balance
    web3.eth.getBalance(address, (err, bal) => {
      if (err) {
        console.log(`getBalance error: ${err}`);
      } else {
        balance = bal;
        console.log(`Balance [${address}]: ${web3.fromWei(balance, "ether")}`);

    Is this still the best approach?

    Since geth v1.7.3 there is debug_getModifiedAccountsByNumber but it is not documented in the wiki yet, you have to take a look at the pull request github.com/ethereum/go-ethereum/pull/15512.
