<p>The <code>Edge Positioning</code> module uses probability to calculate your win rate and risk reward ration. It will use these statistics to control your strategy trade entry points, position side and, stoploss. </p>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p><code>Edge positioning</code> is not compatible with dynamic (volume-based) whitelist.</p>
</div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p><code>Edge Positioning</code> only considers <em>its own</em> buy/sell/stoploss signals. It ignores the stoploss, trailing stoploss, and ROI settings in the strategy configuration file.
<code>Edge Positioning</code> improves the performance of some trading strategies and <em>decreases</em> the performance of others.</p>
</div>
<h2 id="introduction">Introduction<a class="headerlink" href="#introduction" title="Permanent link">&para;</a></h2>
<p>Trading strategies are not perfect. They are frameworks that are susceptible to the market and its indicators. Because the market is not at all predictable, sometimes a strategy will win and sometimes the same strategy will lose.</p>
<p>To obtain an edge in the market, a strategy has to make more money than it loses. Making money in trading is not only about <em>how often</em> the strategy makes or loses money. </p>
<div class="admonition tip">
<p class="admonition-title">It doesn't matter how often, but how much!</p>
<p>A bad strategy might make 1 penny in <em>ten</em> transactions but lose 1 dollar in <em>one</em> transaction. If one only checks the number of winning trades, it would be misleading to think that the strategy is actually making a profit.</p>
</div>
<p>The Edge Positioning module seeks to improve a strategy's winning probability and the money that the strategy will make <em>on the long run</em>. </p>
<p>We raise the following question<sup id="fnref:1"><a class="footnote-ref" href="#fn:1">1</a></sup>:</p>
<div class="admonition question">
<p class="admonition-title">Which trade is a better option?</p>
<p>a) A trade with 80% of chance of losing 100$ and 20% chance of winning 200$<br/>
b) A trade with 100% of chance of losing 30$</p>
</div>
<details class="info" open="open">
<summary>Answer</summary>
<p>The expected value of <em>a)</em> is smaller than the expected value of <em>b)</em>.<br/>
Hence, <em>b</em>) represents a smaller loss in the long run.<br/>
However, the answer is: <em>it depends</em></p>
</details>
<p>Another way to look at it is to ask a similar question:</p>

<p>Let's call <span class="arithmatex">\(o\)</span> the return of a single transaction <span class="arithmatex">\(o\)</span> where <span class="arithmatex">\(o \in \mathbb{R}\)</span>. The collection <span class="arithmatex">\(O = \{o_1, o_2, ..., o_N\}\)</span> is the set of all returns of transactions made during a trading session. We say that <span class="arithmatex">\(N\)</span> is the cardinality of <span class="arithmatex">\(O\)</span>, or, in lay terms, it is the number of transactions made in a trading session.</p>
<div class="admonition example">
<p class="admonition-title">Example</p>
<p>In a session where a strategy made three transactions we can say that <span class="arithmatex">\(O = \{3.5, -1, 15\}\)</span>. That means that <span class="arithmatex">\(N = 3\)</span> and <span class="arithmatex">\(o_1 = 3.5\)</span>, <span class="arithmatex">\(o_2 = -1\)</span>, <span class="arithmatex">\(o_3 = 15\)</span>.</p>
</div>
<p>A winning trade is a trade where a strategy <em>made</em> money. Making money means that the strategy closed the position in a value that returned a profit, after all deducted fees. Formally, a winning trade will have a return <span class="arithmatex">\(o_i &gt; 0\)</span>. Similarly, a losing trade will have a return <span class="arithmatex">\(o_j \leq 0\)</span>. With that, we can discover the set of all winning trades, <span class="arithmatex">\(T_{win}\)</span>, as follows:</p>
<div class="arithmatex">\[ T_{win} = \{ o \in O | o &gt; 0 \} \]</div>
<p>Similarly, we can discover the set of losing trades <span class="arithmatex">\(T_{lose}\)</span> as follows:</p>
<div class="arithmatex">\[ T_{lose} = \{o \in O | o \leq 0\} \]</div>
<div class="admonition example">

<h3 id="win-rate-and-lose-rate">Win Rate and Lose Rate<a class="headerlink" href="#win-rate-and-lose-rate" title="Permanent link">&para;</a></h3>
<p>The win rate <span class="arithmatex">\(W\)</span> is the proportion of winning trades with respect to all the trades made by a strategy. We use the following function to compute the win rate:</p>
<div class="arithmatex">\[W = \frac{|T_{win}|}{N}\]</div>
<p>Where <span class="arithmatex">\(W\)</span> is the win rate, <span class="arithmatex">\(N\)</span> is the number of trades and, <span class="arithmatex">\(T_{win}\)</span> is the set of all trades where the strategy made money.</p>
<p>Similarly, we can compute the rate of losing trades:</p>
<div class="arithmatex">\[
L = \frac{|T_{lose}|}{N}
\]</div>
<p>Where <span class="arithmatex">\(L\)</span> is the lose rate, <span class="arithmatex">\(N\)</span> is the amount of trades made and, <span class="arithmatex">\(T_{lose}\)</span> is the set of all trades where the strategy lost money. Note that the above formula is the same as calculating <span class="arithmatex">\(L = 1 – W\)</span> or <span class="arithmatex">\(W = 1 – L\)</span></p>
<h3 id="risk-reward-ratio">Risk Reward Ratio<a class="headerlink" href="#risk-reward-ratio" title="Permanent link">&para;</a></h3>
<p>Risk Reward Ratio (<span class="arithmatex">\(R\)</span>) 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. Formally:</p>
<div class="arithmatex">\[ R = \frac{\text{potential_profit}}{\text{potential_loss}} \]</div>
<details class="example" open="open">
<summary>Worked example of <span class="arithmatex">\(R\)</span> calculation</summary>
<p>Let's say that you think that the price of <em>stonecoin</em> today is 10.0$. You believe that, because they will start mining stonecoin, it will go up to 15.0$ tomorrow. There is the risk that the stone is too hard, and the GPUs can't mine it, so the price might go to 0$ tomorrow. You are planning to invest 100$, which will give you 10 shares (100 / 10).</p>
<p>Your potential profit is calculated as:</p>
<p><span class="arithmatex">\(\begin{aligned}
\text{potential_profit} &amp;= (\text{potential_price} - \text{entry_price}) * \frac{\text{investment}}{\text{entry_price}} \\
&amp;= (15 - 10) * (100 / 10) \\
&amp;= 50
\end{aligned}\)</span></p>
<p>Since the price might go to 0$, the 100$ dollars invested could turn into 0.</p>
<p>We do however use a stoploss of 15% - so in the worst case, we'll sell 15% below entry price (or at 8.5$).</p>
<p><span class="arithmatex">\(\begin{aligned}
\text{potential_loss} &amp;= (\text{entry_price} - \text{stoploss}) * \frac{\text{investment}}{\text{entry_price}} \\
&amp;= (10 - 8.5) * (100 / 10)\\
&amp;= 15
\end{aligned}\)</span></p>
<p>We can compute the Risk Reward Ratio as follows:</p>
<p><span class="arithmatex">\(\begin{aligned}
R &amp;= \frac{\text{potential_profit}}{\text{potential_loss}}\\
&amp;= \frac{50}{15}\\
&amp;= 3.33
\end{aligned}\)</span><br>
What it effectively means is that the strategy have the potential to make 3.33$ for each 1$ invested.</p>
</details>
<p>On a long horizon, that is, on many trades, we can calculate the risk reward by dividing the strategy' average profit on winning trades by the strategy' average loss on losing trades. We can calculate the average profit, <span class="arithmatex">\(\mu_{win}\)</span>, as follows:</p>
<div class="arithmatex">\[ \text{average_profit} = \mu_{win} = \frac{\text{sum_of_profits}}{\text{count_winning_trades}} = \frac{\sum^{o \in T_{win}} o}{|T_{win}|} \]</div>
<p>Similarly, we can calculate the average loss, <span class="arithmatex">\(\mu_{lose}\)</span>, as follows:</p>
<div class="arithmatex">\[ \text{average_loss} = \mu_{lose} = \frac{\text{sum_of_losses}}{\text{count_losing_trades}} = \frac{\sum^{o \in T_{lose}} o}{|T_{lose}|} \]</div>
<p>Finally, we can calculate the Risk Reward ratio, <span class="arithmatex">\(R\)</span>, as follows:</p>
<div class="arithmatex">\[ R = \frac{\text{average_profit}}{\text{average_loss}} = \frac{\mu_{win}}{\mu_{lose}}\\ \]</div>
<details class="example" open="open">
<summary>Worked example of <span class="arithmatex">\(R\)</span> calculation using mean profit/loss</summary>
<p>Let's say the strategy that we are using makes an average win <span class="arithmatex">\(\mu_{win} = 2.06\)</span> and an average loss <span class="arithmatex">\(\mu_{loss} = 4.11\)</span>.<br>
We calculate the risk reward ratio as follows:<br>
<span class="arithmatex">\(R = \frac{\mu_{win}}{\mu_{loss}} = \frac{2.06}{4.11} = 0.5012...\)</span></p>
</details>
<h3 id="expectancy">Expectancy<a class="headerlink" href="#expectancy" title="Permanent link">&para;</a></h3>
<p>By combining the Win Rate <span class="arithmatex">\(W\)</span> and and the Risk Reward ratio <span class="arithmatex">\(R\)</span> to create an expectancy ratio <span class="arithmatex">\(E\)</span>. A expectance ratio is the expected return of the investment made in a trade. We can compute the value of <span class="arithmatex">\(E\)</span> as follows:</p>
<div class="arithmatex">\[E = R * W - L\]</div>
<div class="admonition example">
<p class="admonition-title">Calculating <span class="arithmatex">\(E\)</span></p>
<p>Let's say that a strategy has a win rate <span class="arithmatex">\(W = 0.28\)</span> and a risk reward ratio <span class="arithmatex">\(R = 5\)</span>. What this means is that the strategy is expected to make 5 times the investment around on 28% of the trades it makes. Working out the example:<br>
<span class="arithmatex">\(E = R * W - L = 5 * 0.28 - 0.72 = 0.68\)</span>
<br></p>
</div>
<p>The expectancy worked out in the example above means that, on average, this strategy' trades will return 1.68 times the size of its losses. Said another way, the strategy makes 1.68$ for every 1$ it loses, on average. </p>
<p>This is important for two reasons: First, it may seem obvious, but you know right away that you have a positive return. Second, you now have a number you can compare to other candidate systems to make decisions about which ones you employ.</p>
<p>It is important to remember that any system with an expectancy greater than 0 is profitable using past data. The key is finding one that will be profitable in the future.</p>
<p>You can also use this value to evaluate the effectiveness of modifications to this system.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>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.</p>

<p>Edge combines dynamic stoploss, dynamic positions, and whitelist generation into one isolated module which is then applied to the trading strategy. 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 <em>N</em> trades for each stoploss. Here is an example:</p>

<p>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 <span class="arithmatex">\(3%\)</span> leads to the maximum expectancy according to historical data.</p>
<p>Edge module then forces stoploss value it evaluated to your strategy dynamically.</p>
<h3 id="position-size">Position size<a class="headerlink" href="#position-size" title="Permanent link">&para;</a></h3>
<p>Edge dictates the amount at stake for each trade to the bot according to the following factors:</p>
<ul>
<li>Allowed capital at risk</li>
<li>Stoploss</li>
</ul>
<p>Allowed capital at risk is calculated as follows:</p>
<div class="highlight"><pre><span></span><code>Allowed capital at risk = (Capital available_percentage) X (Allowed risk per trade)
</code></pre></div>
<p>Stoploss is calculated as described above with respect to historical data.</p>
<p>The position size is calculated as follows:</p>
<div class="highlight"><pre><span></span><code>Position size = (Allowed capital at risk) / Stoploss
</code></pre></div>
<p>Example:</p>
<p>Let's say the stake currency is <strong>ETH</strong> and there is <span class="arithmatex">\(10\)</span> <strong>ETH</strong> on the wallet. The capital available percentage is <span class="arithmatex">\(50%\)</span> and the allowed risk per trade is <span class="arithmatex">\(1\%\)</span>. Thus, the available capital for trading is <span class="arithmatex">\(10 * 0.5 = 5\)</span> <strong>ETH</strong> and the allowed capital at risk would be <span class="arithmatex">\(5 * 0.01 = 0.05\)</span> <strong>ETH</strong>.</p>
<ul>
<li><strong>Trade 1:</strong> The strategy detects a new buy signal in the <strong>XLM/ETH</strong> market. <code>Edge Positioning</code> calculates a stoploss of <span class="arithmatex">\(2\%\)</span> and a position of <span class="arithmatex">\(0.05 / 0.02 = 2.5\)</span> <strong>ETH</strong>. The bot takes a position of <span class="arithmatex">\(2.5\)</span> <strong>ETH</strong> in the <strong>XLM/ETH</strong> market.</li>
</ul>
<ul>
<li><strong>Trade 2:</strong> The strategy detects a buy signal on the <strong>BTC/ETH</strong> market while <strong>Trade 1</strong> is still open. <code>Edge Positioning</code> calculates the stoploss of <span class="arithmatex">\(4\%\)</span> on this market. Thus, <strong>Trade 2</strong> position size is <span class="arithmatex">\(0.05 / 0.04 = 1.25\)</span> <strong>ETH</strong>.</li>

<div class="admonition tip">

Since <strong>Trade 1</strong> has <span class="arithmatex">\(2.5\)</span> <strong>ETH</strong> blocked and <strong>Trade 2</strong> has <span class="arithmatex">\(1.25\)</span> <strong>ETH</strong> blocked, there is only <span class="arithmatex">\(5 - 1.25 - 2.5 = 1.25\)</span> <strong>ETH</strong> available.

<li><strong>Trade 4</strong> The strategy detects a new buy signal int the <strong>XLM/ETH</strong> market. <code>Edge Positioning</code> calculates the stoploss of <span class="arithmatex">\(2%\)</span>, and the position size of <span class="arithmatex">\(0.055 / 0.02 = 2.75\)</span> <strong>ETH</strong>.</li>

<p>Edge produced the above table by comparing <code>calculate_since_number_of_days</code> to <code>minimum_expectancy</code> to find <code>min_trade_number</code> historical information based on the config file. The timerange Edge uses for its comparisons can be further limited by using the <code>--timerange</code> switch.</p>
<p>In live and dry-run modes, after the <code>process_throttle_secs</code> has passed, Edge will again process <code>calculate_since_number_of_days</code> against <code>minimum_expectancy</code> to find <code>min_trade_number</code>. If no <code>min_trade_number</code> is found, the bot will return "whitelist empty". Depending on the trade strategy being deployed, "whitelist empty" may be return much of the time - or <em>all</em> of the time. The use of Edge may also cause trading to occur in bursts, though this is rare.</p>
<p>If you encounter "whitelist empty" a lot, condsider tuning <code>calculate_since_number_of_days</code>, <code>minimum_expectancy</code> and <code>min_trade_number</code> to align to the trading frequency of your strategy.</p>
