Sharpe ratio signal

Hello,

I wanted to know if there is a difference between the sharpe ratio given on the matatrader software when we do a test and the one given in the signals?

Curiously, it seems that the value of the sharpe ratio is not the one generally known?

Thanks.

Good .... It seems that the sharpe ratio generally used is the one used in test reporting. This is the one we find when we look at the mql doc at this link: https://www.metatrader5.com/en/terminal/help/algotrading/testing_report

However for the signal it seems that it is not the same and we see it on the help page for the search for an mt5 signal at this link: https://www.metatrader5.com/en/terminal/help/signals/signal_monitoring

We notice that in the statistical explanations of a signal the unit of the sharpe ratio is in "%"??

A Google search does not direct me to a sharpe ratio in percentage, so I come to ask my question here.

You can view a detailed report on the "Results" tab. The following parameters are available in the testing report: History Quality — this...

I think - it is error as it is not in "%".
I mean: same Sharpe calculation for strategy tester and for the signal page.

Je pense - c'est une erreur car ce n'est pas dans "%".
Je veux dire : même calcul de Sharpe pour le testeur de stratégie et pour la page de signal.
I find it strange that despite a lot of research I can't find a signal with a sharpe ratio greater than 1. It just seems that the calculation is different. I compared backtests between some trading systems and their online signal, it's not the same ratio at all. The difference is not minimal and is great I am talking about a signal where the ratio is 0.25 in signal and in back test I have a ratio greater than 3! that's a big difference.

This is indeed interesting! At the moment I don't have time, but in this article is a script to calculates the sharp ration. And as there are some quite profitable signals and they all offer their trade history one can easily check - I'll do it over the weekend.

Return on investments is the most obvious indicator which investors and novice traders use for the analysis of trading efficiency. Professional traders use more reliable tools to analyze strategies, such as Sharpe and Sortino ratios, among others.

Most likely a different risk free rate is used, hence a different ratio.

There are Sharpe Ratio, Modified Sharpe Ratio and Annual Sharpe Ratio, and this all is described in the following:

The Sharpe Ratio
William F. Sharpe
Stanford University

I do not know which Sharpe Ratio is used for the signal.
But the Sharpe ratio is mostly used for porfolio trading/estimation, and this is not a portfolio (we can subscribe to one signal only by one trading account).
And that is why the users are not looking at Sharpe Ration in most of the cases.

Frankly, I don't mind, but normally there should be a signal where the sharpe ratio is greater than 1? But hey, it seems that there is none... even trading solutions which in backtest have a ratio of 40 are below 1 on their signal.

If a different calculation is used, I would just like to succeed in transcribing it into what we know to find limits that speak to me, in particular having a signal greater than 2... which is normally the minimum to have for us to be interested in it.

It's just that if I follow the principle of the info bubble that appears when you place the cursor over it. It seems that for the screen that I took we are risking \$10 to win \$1.2 and that once again seeing that there is no signal with a ratio greater than 1 it seems impossible to say I risked \$10 to win \$20 sharpe ratio = 2.

I'm going to read the report you put in (it's going to take some time).

Study the formula. The calculation is the same, the risk free rate is different. There is no point in sharpe ratio on the website, tester etc. Your risk free rate might be different from mine.

Because the risk free rate change over time, there is no such thing as "should be this or that value".
