Hi, I was wondering is there any specific reason to why the minimum order size is at £2? I personally would like it to be around £1 for a few reasons:
I assume different people will want the minimum order size to be at different levels for their needs, but I think lowering the minimum order sizer from £2 to £1 will be a nice change and it helps the smaller portfolio use their spare money more. Thank you.
I’m sure someone can come in with a more detailed explanation but for a quick answer:
The minimum order used to be £1 before US fractionals were introduced earlier this year. Then the minimum was bumped to £2. I think think the explanation given then was it relates to an actual minimum order needing to be £1 in order to execute, so the minimum order is set to £2 in order to eliminate any risk of volatile FX fluctuations suddenly dropping the order value to under £1 during execution.
e.g. an order sent at the value of £2 might actually be executed at the price of ~£1.98 during volatile FX fluctuations, this avoids the instance where a £1 order would be executed at ~£0.99 - below the minimum order value.
That actually makes a lot of sense, thank you. 
There actually was no minimum pre fractionals, I used to throw pennies into random stocks.
I wouldn’t have thought the £2 minimum would apply to dividend reinvestment, when that gets introduced
I assume you mean when auto dividend reinvestment/DRIP is added. If so, then based on @MJE’s explanation, it looks like it might be there as well.
I was thinking this would be a bulk order (or similar) for all clients and so would avoid that issue. This would be more efficient than individual trades
