The evolution of brokerage trading technology is nothing short of astounding. Trading has ceased to be a prerogative of institutional traders only. Today, anyone with a computer and internet access can access global financial markets and trade from virtually anywhere in the world. This revolutionary change is mainly due to the development of online trading platforms from software giants like MetaTrader and Interactive Brokers' Trader WorkStation (TWS). Both platforms come with powerful Application Programming Interfaces (APIs) that open the door for developers to build custom trading applications. This article explores the ins and outs of trading platform development using MetaTrader or TWS API.

MetaTrader API

MetaTrader from Metaquotes Software Corp. is arguably the most popular among retail traders. It offers two premier trading platforms, namely, MetaTrader 4 (MT4) and MetaTrader 5 (MT5). Both editions support automated trading through Expert Advisors and carry API infrastructure that allows developers to build and integrate custom software.

MetaTrader APIs provide direct access to the components of the MetaTrader platform. They allow the creation of applications that interact with the platform and execute operations on behalf of the user. Moreover, they enable communication with the platform without going through the graphical interface. This provides flexibility for developers to build software applications ranging from simple novelty indicators to high-frequency algorithmic trading systems. Note, the current version, MT5, supports a broader scope of operations compared to MT4, including, but not limited to, trading, streaming of price quotes, account management, and testing of trading strategies.

There are two main types of APIs in MetaTrader: the Manager API and the Server API. The Manager API facilitates the creation of system utilities to handle account and order management, while the Server API enables developers to build their own custom servers.

Interactive Brokers' TWS API

Interactive Brokers (IB) TWS is mainly used by professional traders and investors. It, too, has an API, referred to as TWS API, that allows third-party developers to build applications that interact with the platform. The TWS API is an interface to IB’s standalone trading applications, TWS and IB Gateway.

The TWS API enables developers to build trading applications that can: automate trading, retrieve streaming and historical market data, access account data, implement trading algorithms, execute trades, and manage open orders and portfolios.

The key feature that sets TWS API apart is its support for multiple programming languages, including but not limited to Java, Python, C++, and .NET (C#). With TWS API, you can perform tasks such as managing real-time data feed, submitting complex multi-leg order types, managing account balances, and receiving live trading notifications.

Choosing between MetaTrader and TWS API

Choosing between the two largely depends on your specific needs. MetaTrader tends to be more popular among retail traders, particularly in the FOREX market due to its user-friendly interface and comprehensive charting capabilities. On the other hand, TWS suits institutional and professional traders better due to its sophisticated trading tools and wide range of tradable securities.

In conclusion, both MetaTrader and TWS bring the financial markets to your fingertips. They both offer powerful APIs that can go a long way in custom trading application development. It is worth noting that trading platform development is a sophisticated technical project that requires a deep understanding of both trading and programming. Therefore, it would be wise to consult with a professional tech enterprise to bring your trading vision to life.

The recent plunge in Bitcoin (BTC) prices, which saw the cryptocurrency drop below $55,000, has not shaken the confidence of blockchain developers.
Despite the volatility, they remain focused on building innovative applications and infrastructure to support the long-term growth of the Bitcoin network.

"While the price decline is concerning in the short term, we are not changing our development roadmap," said Sarah Tan, lead developer at a prominent blockchain startup in Singapore.
"Our goal is to create products that provide real utility and value to users, regardless of market conditions."

One key area of focus for many blockchain developers is improving the scalability and efficiency of the Bitcoin network.
With the recent halving event reducing block rewards, miners are facing increased pressure to optimise their operations.
Developers are working on solutions like the Lightning Network to enable faster and cheaper transactions, helping to maintain the network's viability.

"Volatility is part of the game in crypto," said Mike Lim, a veteran blockchain engineer in Singapore. "We've seen these cycles before, and the best way to weather them is to keep our heads down and deliver quality code that solves real problems."

Despite the challenges, many Blockchain developers remain optimistic about Bitcoin's long-term prospects.
The increasing institutional adoption and the potential for new applications like decentralised finance (DeFi) and non-fungible tokens (NFTs) on the Bitcoin network provide reasons for optimism.

"Bitcoin has proven its resilience time and again," said Tan. "As long as we stay focused on building useful products and expanding the ecosystem, I believe the price will take care of itself in the long run."

Ultimately, while the price decline may cause short-term uncertainty, blockchain developers remain committed to their mission of advancing the technology and driving mainstream adoption.
By continuing to innovate and create value for users, they aim to weather the storm and emerge stronger on the other side.

Developing Smart Contracts for Cross-Chain Operations: A Comprehensive Guide

Vincent Lee — Wed, 03 Jul 2024 18:28:07 +0000

Smart contracts coding is a pivotal part of blockchain development, with Solidity being the primary language for creating them on Ethereum.
However, as the blockchain universe expands, cross-chain or interoperable solutions have gained traction.
This article enlightens how to develop smart contracts on a cross-chain platform, specifically focusing on how they can operate seamlessly among diverse blockchain networks.

Cross-Chain Technology Overview

Cross-chain technology facilitates interaction and interoperability among different blockchain networks.
It allows transactions to occur between distinct blockchains, thus overcoming the limitations of blockchain networks operating in silos.
The ability for multiple, disparate blockchains to communicate and share information is revolutionary for the digital ledger technology field.

Understanding Cross-Chain Smart Contracts

Developing a cross-chain smart contract involves creating a decentralized application that operates on multiple blockchains without compromising its functionality.
For instance, converting ERC20 tokens (native to the Ethereum platform) into BEP2 tokens (native on the Binance chain).

Tools for Developing Cross-Chain Smart Contracts

Several tools and platforms offer the interoperability needed for cross-chain smart contracts deployment.
Key players in this field include Polkadot, Cosmos, and Chainlink.

Creating a Simple Cross-Chain Smart Contract

Let’s create a simple cross-chain smart contract using Solidity and Chainlink.
This contract will interact with multiple blockchains like Ethereum and Binance Smart Chain.

Notice: You need to have a Metamask account, Rinkeby testnet Ether, and BNB (binance coin for testing on Binance Smart Chain).

solidity
pragma solidity ^0.7.3;

import "@chainlink/contracts/src/v0.7/ChainlinkClient.sol";

contract CrossChainContract is ChainlinkClient {

    uint256 oraclePayment;

    constructor() public {
        setPublicChainlinkToken();
        oraclePayment = 0.1 * 10 ** 18; 
    }

    function requestEthereumPrice() public returns (bytes32 requestId) {
        Chainlink.Request memory request = buildChainlinkRequest(
            jobid, 
            address(this), 
            this.fulfill.selector
        );
        request.add("get", "https://eth-price-feed.com/");
        return sendChainlinkRequestTo(oracle, request, oraclePayment);
    }

    function fulfill(bytes32 _requestId, uint256 _payment) public recordChainlinkFulfillment(_requestId) {
        oraclePayment = _payment;
    }
}

In this simple contract:

ChainlinkClient is inherited so we can connect to Chainlink nodes.
oraclePayment represents the amount paid to the Chainlink node for data.
The Constructor sets the Link token as the standard currency for payment.
requestEthereumPrice creates a Chainlink request and sends it.
fulfill function receives the data from Chainlink and can then be used within our smart contract.

Once ready, deploy these contracts on your chosen blockchains.
Make sure to set the right parameters for the Chainlink node and contract addresses.
With these contracts, we can obtain and incorporate data from multiple chains and create truly interoperable dApps.

Keep in mind that the complexity of your smart contract will depend on the specifics of your project—this is just an elementary example.
Test your contracts thoroughly before deploying them to mainnet networks.

The future of blockchain technology lies in the capability to seamlessly integrate various blockchain platforms, and cross-chain smart contracts are at the heart of this development.
Thus, honing skills in this area will make you an invaluable asset in the ever-evolving blockchain industry.
