arrowsdrawline
How can I draw a graph like the one in the picture?
I'm fairly new to Latex and I only know that I can draw lines with \line or \hrule but I have no clue how to draw a graph like this…
In addition I would like to put two arrows in front of the horizontal line (in front of the day market), with some additional text (for two actions happening before the day market).
A @whlt3 mentioned in the comments, adding the -> option to the draw command will produce an arrow. There are different arrow option available, and below I have used -latex as I think that looked better in this case. In the linked question Drawing Arrows in Tables the arrow style -triangle 45 was used so may not have been obvious. A few of the arrow types are mentioned at Graph into graph with arrows, but many more are available -- see the TikZ/PGF documentation for more arrow options.
However, in this case I would also recommend that you also adapt a slightly different syntax so that you can specify the out and in angle for the line so that provide flexibility in case the straight line would overlap some other code to yield:
\documentclass[border=5pt]{standalone}
\usepackage{listings}% http://ctan.org/pkg/listings
\usepackage{tikz}% http://ctan.org/pkg/pgf
\usetikzlibrary{calc}

\newcommand{\tikzmark}[1]{\tikz[overlay,remember picture] \node (#1) {};}
\lstset{
frame=single,
mathescape % Allows escaping to (La)TeX mode within $..$
}
\begin{document}
\noindent\begin{minipage}{.45\textwidth}
\begin{lstlisting}[caption={Original code}]
1 code $\tikzmark{L1line1}$
2 some longer code here
3 some longer code here
4 more code$\tikzmark{L1line4}$
\end{lstlisting}
\end{minipage}\hfill
\begin{minipage}{.5\textwidth}
\begin{lstlisting}[caption={Code after insertion of detour}]
$\tikzmark{L2line1}$ 86
$\tikzmark{L2line4}$ 4
\end{lstlisting}
\end{minipage}
\tikz[overlay,remember picture,-latex] \draw[color=red,thick,out=0,in=160] ($(L1line1)+(0pt,0.7ex)$) to ($(L2line1)+(0pt,0.7ex)$);
\tikz[overlay,remember picture,-latex] \draw[color=blue,thick,out=0,in=200] ($(L1line4)+(0pt,0.7ex)$) to ($(L2line4)+(0pt,0.7ex)$);
\end{document}
You can use the (p |- q) notation, meaning the intersection of a vertical line through p and a horizontal line through q.
\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[auto]
\node (S1) {$\sigma \cap X_N$};
\node (S2) [below= 2cm and 4cm of S1] {$\sigma \cap X_N$};
\node (S3) [below= 2cm and 4cm of S2] {$\sigma$};
\node (U1) [right= 2cm and 4cm of S1] {$\gamma$};
\node (U2) at (U1 |- S2) {$Y_M$};
\node (U3) at (U2 |- S3) {$R^M$};
\draw[->] (S1) to node {$F_f$} (U1);
\draw[->] (S2) to node {$\widetilde{F}_f$} (U2);
\draw[->] (S3) to node {$\widehat{F}_f$} (U3);
\draw[->] (S1) to node [swap] {$I$} (S2);
\draw[->] (S2) to node [swap] {$\theta_{B_N}$} (S3);
\draw[->] (U1) to node {$P^{\hat{E}{\cdot}{\cdot}}_{Y_M}$} (U2);
\draw[->] (U2) to node {$\theta_{C_M}$} (U3);
\end{tikzpicture}
\end{document}

as starting point ...
Edit: instead of
>={Bar[width=4mm]}is defined new style for vectors:Vect/.style = {very thick, Bar[width=4mm]}and accordingly changed code for line.
