Hi guys - looking for an opinion as I know there is a wealth of knowledge here on this platform. 

I have been investing for a fair amount of time, with the majority of capital in my portfolio allocated to an actively managed investment fund - Alliance Trust ($ATST (+0 %) ) - now called Alliance Witan (ALW) after merger but does not show on getquin. 

I am however lacking expertise on ETF portfolios and would love some speculation into my consideration.

I’m wanting to create a long term ETF portfolio with moderate risk. I’m thinking of setting the majority to $VWCE (-0,15 %) around (80%) but am interested to hear any other ETFs you guys know of that pair well? I do like to keep simplicity as I found it has generated the greatest returns for me in the past, however I do like to include a small amount of more ‘riskier’ investments in my portfolio. I was considering adding 10% $XDWT (-0,19 %) - but thought this might be too tech heavy and dependant. I’d love to hear anyones suggestions on potential ETFs to include.

Im thinking of using the capital from ($ATST (+0 %) / ALW). This would be the sole funding of the ETF.

The amount I’m going to be using to invest in this ETF is around £18,000 as I want this ETF to be separate. 

What would your opinions be on:

Selling £18,000 shares of (ATST/ALW) to use in an ETF Mix?

The risk/reward trade off between (ATST/ALW) and VWRA long term?

Potential alternative ETFs or combinations?  

Whether or not to lump sum £18,000 or DCA? 

Any precautions Trumps 4 years will bring to this investment choice?

Really appreciate any opinions! :)
