同时支持 ISA 帐户和 API 访问的经纪商？
我正在寻找一位股票经纪人，但似乎找不到一位“符合所有条件”的经纪人 - 有人可以帮忙吗？！
基本要求是：
- 支持股票 ISA 账户
- 访问伦敦证交所的 ETF，尤其是 iShares
- 实时价格信息/交易（尽可能低的延迟）
- 低费用/收费（最好有大幅折扣例如每周超过 10 笔交易）
- 适用于个人，而不仅仅是机构
仅执行即可，不需要任何花哨的东西。我猜 ISA 要求可能仅限于英国经纪商。有很多经纪商可以完成上述所有操作，所以这归结为我的关键额外要求：
- API 访问，例如 FIX（用于自动/算法交易）
但我找不到任何经纪商同时具有 ISA 支持和 API 访问权限。我想这一定不是英国个人投资者的常见要求，但美国经纪人似乎很常见。如果确实有必要的话，我也许可以在没有 API 访问的情况下生活。 （只要有一个网络界面，现在他们似乎都这样做了。而且我对桌面/移动交易平台软件没有要求。）
我的“非常想要，但可以灵活处理”的要求是：
- Marketcetera 或类似的现有（开源/廉价）连接器
- 以合理的价格实时 2 级价格信息 以
- 合理的价格在伦敦证券交易所 (LSE) 上进行 DMA（直接市场准入）（最好没有大规模的“专业客户”流程必须经过）
那么可选的/“最好有的是：
- 用于测试的演示/“垄断货币”账户
- 超低延迟定价/交易
- 可以切换到差价合约/点差交易
- 还支持 SIPP
那么，有谁知道有哪些经纪商满足某些要求/所有这些要求？
我发现满足我基本要求的最便宜的是 xo.co.uk 和 hl.co.uk，目前两者的收费均为 5.95 英镑。还有 share.com，其高级帐户将来可能会很有用，但前期费用相当昂贵 - 每年 3000 英镑，可以无限次交易，没有其他主要费用。 E*TRADE 可能已经完成了这项工作，但他们不再在英国进行交易。 Interactive Brokers 似乎是英国 API 访问的唯一选择（？），但他们不支持 ISA。 （他们说“经过审查后，我们决定目前不支持 ISA。”所以这不会很快发生。）有一些看起来不错的平台，例如 Marketcetera/JBookTrader/tradelink/ActiveQuant - 但如果他们无法连接到执行 ISA 的代理，他们为我的目的而烦恼。
我在思考时还有一些其他问题：
有人知道普通英国零售经纪商网络界面的“实时”价格/交易实际上有多少延迟吗？
不同经纪商的股票价格几乎相同吗？我在某处的评论中读到，一家经纪人提供的股票价格不如其他经纪人？！这是否取决于他们使用的 RSP？
是否有可能以合理的价格在 LSE 上获得 DMA，而无需经历大量的“专业客户”流程？
I'm looking for a stockbroker but can't seem to find one that 'ticks all the right boxes' - can anyone help please?!
The essential requirements are:
- Supports Shares ISA accounts
- Access to ETFs on the LSE, especially iShares
- Real-time price info/trading (with as low latency as possible)
- Low fees/charges (preferably with a heavy discount for say 10+ trades per week)
- Available to individuals, not just institutions
Execution-only is fine, don't need anything fancy. The ISA requirement probably restricts it to UK brokers I guess. There are loads of brokers that do all of the above, so then it comes down to my key additional requirement:
- API access, e.g. FIX (for automated/algorithmic trading)
But I can't find any brokers that have both ISA support and API access. I guess it mustn't be a common requirement for individual investors in the UK but it seems commonly available from US brokers. I can probably live without API access if I really have to. (As long as there's a web interface, which they all seem to do nowadays. And I have no requirement for desktop/mobile trading platform software.)
My 'would really like but can be flexible on' requirements are:
- Existing (open source/cheap) connector for Marketcetera or similar
- Real-time level 2 price info at a reasonable price
- DMA (Direct Market Access) on the LSE at a reasonable price (preferably without a massive 'professional client' process to have to go through)
Then the optional/'nice to have's are:
- Demo/'monopoly money' account for testing
- Ultra low latency pricing/trades
- Can switch into CFDs/spreadbetting
- Also supports SIPPs
So, does anyone know of any brokers that meet some/all these requirements?
The cheapest ones I've found that meet my essential requirements are x-o.co.uk and hl.co.uk, both currently charging £5.95. There's also share.com whose Premium account might be useful in the future but rather pricey up front - £3000 per year for unlimited trades with no other major charges. E*TRADE might have done the job but they're no longer trading in the UK. Interactive Brokers seems to be the only choice for API access in the UK (?) but they don't support ISAs. (They've said "After reviewing this we have decided not to support ISA's at this time." so it won't happen anytime soon.) There are some nice-looking platforms like Marketcetera/JBookTrader/tradelink/ActiveQuant - but if they can't connect to a broker that does ISAs they're skuppered for my purposes.
And some additional questions while I'm thinking:
Anyone know how much latency there actually is on a normal UK retail broker's web interface's "real-time" prices/trades?
Are stock prices pretty much the same across different brokers? I read in a review somewhere that one broker didn't offer as good a stock prices as others?! Is this down to the RSPs they use maybe?
Is it even possible to get DMA on the LSE at a reasonable price without a massive 'professional client' process to have to go through?

看来 IG 经纪商可能同时拥有 ISA 和 API...似乎找不到任何其他API。
It seems that IG brokers may have both ISAs and and an API... Can't seem to find any others.
