Replace brackets in references with commas in Latex

I would like to replace the brackets of the year with commas in the references as it is the standard method in the Journal of Finance.

In the references, I have this structure; Author (2020) Title... but I would like to change it to; Author, 2020, Title...

This would be a sample bibliography:

@article{examplesource,
  title={Title of article},
  author={LastName1, FirstName1 and LastName2, FirstName2 and LastName3, FirstName3},
  journal={Journal of Finance},
  volume={40},
  number={1},
  pages={3--73},
  year={2005}}

This is what I have so far:

\documentclass{article}

\usepackage[style=ext-authoryear, backend=biber, giveninits=true, uniquelist = false, uniquename=init, isbn=false, maxcitenames=3, dashed=false, maxbibnames=999, doi=false, url=false]{biblatex}

\addbibresource{biblatex-examples.bib}
%\DeclareDelimFormat{nameyeardelim}{\addcomma\space}

\setlength{\bibhang}{15pt}
\DeclareNameAlias{sortname}{family-given}
\renewcommand*{\labelnamepunct}{\addspace}

\DeclareFieldFormat[article,inbook,incollection,inproceedings,patent,thesis,unpublished]{title}{#1}

\DeclareFieldFormat{titlecase}{\MakeSentenceCase*{#1}}

\renewbibmacro*{in:}
    {\ifentrytype{article}
    {\setunit{\addcomma\space}}
    {\printtext{\bibstring{in}\intitlepunct}}}

\DeclareFieldFormat{journaltitlecase}{#1}

\renewbibmacro*{journal}{
  \ifboolexpr{
    test {\iffieldundef{journaltitle}}
    and
    test {\iffieldundef{journalsubtitle}}}
    {\printtext[journaltitle]{
       \printfield[journaltitlecase]{journaltitle}
       \setunit{\subtitlepunct}
       \printfield[journaltitlecase]{journalsubtitle}}}}

\renewbibmacro*{volume+number+eid}{
  \printfield{volume}
  \setunit{\addcomma\space}
  \printfield{eid}}

\DeclareFieldFormat[article,periodical]{volume}{{#1}}

\DeclareFieldFormat{pages}{#1}

\UndeclareInnerCiteDelims{parencite}
\DeclareInnerCiteDelims{parencite}{(}{)}

Thanks a lot for your help!

Luckily you are using the ext-authoryear style, so you can use

  • \DeclareFieldFormat{biblabeldate}{#1} to remove the parenthesis
  • \DeclareDelimFormat[bib]{nameyeardelim}{\addcomma\space} to add a comma before the year
  • \ExecuteBibliographyOptions{innamebeforetitle=true} \DeclareDelimFormat[bib]{nametitledelim}{\addcomma\space} to add a comma after the year
