# EMA Crossovers

Crossing "EMAs" gives indications about possible trading points. Traders can create trades by taking advantage of these intersections.

{% hint style="success" %}
If the short period moving average crosses above the long period moving average , it can be considered as a buy signal. If the short period moving average crosses below the long period moving average , it can be considered as a **sell signal**.
{% endhint %}

Coinlegs software uses the crosses of **EMA5 X EMA20**, **EMA7 X EMA34**, **EMA13 X EMA21**, **EMA20 X EMA50** and **EMA50 X EMA100**.

(E520, E734, E1321, E2050, E50100)
