Answer 1

\documentclass[tikz,border=2mm]{standalone} 
\usetikzlibrary{positioning, arrows.meta}

\begin{document}
\begin{tikzpicture}[font=\itshape]
\foreach \i [count=\xi] in {-2,-1.5,...,2}
    \node (t\xi) at (2*\i,0) {\i};
\node[left = of t1, anchor=center] (time) {Time};
\node[right = of t9, anchor=center] (dots) {\dots};
\draw (time.south west) -- (dots.east|-time.south);

\foreach \i [count=\xi from 0, count=\ni from 5] in {1,2,3,4}{
    \draw[Circle-Circle] ([yshift=-1cm-1.2cm*\xi]t\i.center)--node[above]{formation} ([yshift=-1cm-1.2cm*\xi]t\ni.center);
    \draw[Circle-Circle] ([yshift=-1.5cm-1.2cm*\xi]t\ni.center)--node[above]{trading} ++(0:1);
    }
\end{tikzpicture}
\end{document}
