Mega Securities — FAQ
Does Mega Securities offer an API?
Yes — MegaAPI Speedy (Python/C#/C++，僅 Windows). API access requires an existing account and a separate application; the steps and usage limits are in the sourced answers below, while trading commissions are set by Mega Securities and change — check the official site at www.emega.com.tw.
How do I apply for the Mega API? Does it cost anything?
According to the official FAQ in the Mega Securities API section, the process has three steps: ① First, have a Mega Securities electronic trading account (securities/sub-brokerage and futures accounts can all be opened online); ② Sign the “API (Application Programming Interface) Risk Disclosure and Use Statement” — corporate or minor accounts cannot sign online; you must bring authorization documents and identification to a branch to handle it in person; ③ Download the permission application software and complete the API permission application according to the instructions. The official application instructions also specify that securities and futures and options require separate document signing, and before formal order placement there must be an integration test record (a fixed IP must be provided during testing); access will be activated only after verification is confirmed correct. Orders must use a PFX-format certificate, which can be applied for and renewed via “Certificate e-Point.” The official page does not list an API usage fee.
Does Mega API support Python? Can it be used on Mac or Linux?
Python is supported. The official FAQ states that both the trading and market-data APIs support Python, C#, and C++ (the Speedy Python/C++/C# APIs each have 64-bit and 32-bit versions). However, it cannot be used on Mac or Linux: the official FAQ says, “Currently, due to certificate restrictions, it is supported only in the Windows environment.” In addition, the official service does not provide backtesting services for trading strategy performance, and historical market data currently covers only Taiwan stocks; Mega also notes that it provides only API components and documentation and is not responsible for users’ program development.
Can MegaAPI trade futures, options, and U.S. stocks?
The trading API in the technical documentation covers securities, the emerging stock board, futures (orders, trades, open positions, equity and margin queries), and overseas stocks. The official sample files also come in three sets: securities, futures and options, and U.S. stocks; futures and options trading requires signing a separate Mega Futures API document. For sub-brokerage, the official FAQ states that the API currently supports only U.S. stocks, excludes fractional share trading, and does not currently support integration with market data for overseas products. Those using MultiCharts must also apply for API permissions; for Mega Futures’ MultiCharts brokerage version, see /en/brokers/mega-fut/.
