## Introduction
Trading is all about probability. no one can claim that he has a strategy working all the time. you have to assume that sometimes you lose.<br/><br/>
But it doesn't mean there is no rule, it only means rules should work "most of the time". let's play a game: we toss a coin, heads: I give you 10$, tails: You give me 10$. is it an interetsing game ? no, it is quite boring, isn't it?<br/><br/>
But lets say the probabiliy that we have heads is 80%, and the probablilty that we have tails is 20%. now it is becoming interesting ...
That means 10$ x 80% versus 10$ x 20%. 8$ versus 2$. that means over time you will win 8$ risking only 2$ on each toss of coin.<br/><br/>
lets complicate it more: you win 80% of the time but only 2$, I win 20% of the time but 8$. the calculation is: 80% * 2$ versus 20% * 8$. it is becoming boring again because overtime you win $1.6$ (80% x 2$) and me $1.6 (20% * 8$) too.<br/><br/>
The question is: how do you calculate that? how do you know if you wanna play?

The answer comes to two factors:
- Win Rate
- Risk Reward Ratio

### Risk Reward Ratio
Risk Reward Ratio is a formula used to measure the expected gains of a given investment against the risk of loss. it is basically what you potentially win divided by what you potentially lose:

**NOTICE:** It's important to keep in mind that Edge is testing your expectancy using historical data , there's no guarantee that you will have a similar edge in the future. It's still vital to do this testing in order to build confidence in your methodology, but be wary of "curve-fitting" your approach to the historical data as things are unlikely to play out the exact same way for future trades.
## How does it work?
If enabled in config, Edge will go through historical data with a range of stoplosses in order to find buy and sell/stoploss signals. it then calculates win rate and expectancy over X trades for each stoploss. here is an example:

The goal here is to find the best stoploss for the strategy in order to have the maximum expectancy. in the above example stoploss at 3% leads to the maximum expectancy according to historical data.

Edge then forces stoploss to your strategy dynamically.
