beamer add tag
JeT
I'd like to have a more visual itemization as follows

**Where I need help**

Connect bullets to each other with overlays. 

There must be a `TikZ` solution but the idea of naming each bullet and then connect it with overlays seems beyond of my knowledge :/ 

Edit 1 : I investigate on [this](https://tex.stackexchange.com/questions/91675/tikz-node-at-item-to-use-in-overlay)

**MWE** 

```
\documentclass[aspectratio=169]{beamer}

\setbeamertemplate{itemize item}{\raisebox{-0.1em}{\scalebox{1.8}{$\bullet$}}}
\setbeamertemplate{itemize subitem}[]  % no bullet not working

\begin{document}
\begin{frame}

\begin{itemize}[<+->]
	
	\item Passe \alert{un grand nombre d’ordres d’achat} à des prix plus faibles mais \alert{proches du meilleur prix à l’achat sur ce titre}
	      
	\item \alert{Illusion de liquidité} et de pression sur la \alert{tendance à la hausse}
	      
	\item Passe un ordre unique à la vente
	      
	      \begin{itemize}
	      	\item Vend à un meilleur prix que celui du marché
	      	\item Plus-value plus importante
	      \end{itemize}
	      
	\item \alert{Annuler} les ordres d’achats qui ont permis de pousser le marché à la hausse

One possible approach using a tikz matrix (there is some potential for optimisation, e.g. using tikz styles, so just as a proof of concept):

```
\documentclass[aspectratio=169]{beamer}

\usepackage{tikz}
\usetikzlibrary{overlay-beamer-styles}

\begin{document}

\begin{frame}[t,fragile]
\begin{tikzpicture}
\node [matrix] (my matrix) at (0,0) {
  \usebeamercolor[fg]{itemize item} \fill<+-> (0,0.13) coordinate (a) circle (1mm); &
  \node<.->[text width=.9\linewidth,anchor=base] {Passe \alert{un grand nombre d’ordres d’achat} à des prix plus faibles mais \alert{proches du meilleur prix à l’achat sur ce titre}}; \\
  \usebeamercolor[fg]{itemize item} \fill<+->[blue] (0,0.13) coordinate (b) circle (1mm); &
  \node<.->[text width=.9\linewidth,anchor=base] {\alert{Illusion de liquidité} et de pression sur la \alert{tendance à la hausse}}; \\
  \usebeamercolor[fg]{itemize item} \fill<+->[blue] (0,0.13) coordinate (c) circle (1mm); &
  \node<.->[text width=.9\linewidth,anchor=base] {Passe un ordre unique à la vente
  	      \begin{itemize}
  	      	\item Vend à un meilleur prix que celui du marché
  	      	\item Plus-value plus importante
  	      \end{itemize}
  	};\\
  \usebeamercolor[fg]{itemize item} \fill<+->[blue] (0,0.13) coordinate (d) circle (1mm); &
  \node<.->[text width=.9\linewidth,anchor=base] {\alert{Annuler} les ordres d’achats qui ont permis de pousser le marché à la hausse};\\
  };
  \usebeamercolor[fg]{itemize item}  \draw<2-> [very thick] (a.center) -- (b.center);
  \usebeamercolor[fg]{itemize item}  \draw<3-> [very thick] (b.center) -- (c.center);
  \usebeamercolor[fg]{itemize item}  \draw<4-> [very thick] (c.center) -- (d.center);    
\end{tikzpicture}
\end{frame}

Based on [this answer to count items](https://tex.stackexchange.com/a/74617/163874) and [this answer to use nodes in items](https://tex.stackexchange.com/a/91681/163874),

Unfortunately I cannot make it work with subitems... (counters I have to articulate i presume). With a manual change
