Do not buy into a falling market - you will lose money - simple as.
The ISEQ has dipped 50% in 12 months - building and financial dragging all retail related with it - this is worst case and more is likely to come, this fall is only on the back of a house price crash / recession that is only starting globally, we were one of the boats that rose with a global tide.
The only reason that other more global markets have not been hit similarly is that they have a healthy diversified mix (ie not like the ISEQ dominated by building and financial) - whilst their own building and financial stock dips, the spread of commodity and manufacturing holds up. However guess what happens in a global recession, commodities and manufacturing fail as well thus the ISEQ crash is only a precursor to what will happen to larger equity markets elsewhere. Global equities are not safe currently
Dollar cost averaging only (at best) works in normal trading conditions - nothing at the moment globally is normal, the wheels are coming off the FIRE economies and globalisation is magnifying the bad impacts locally.
At the moment - cash, my friend, is king.
