# Vortex filter

<mark style="color:$tint;">The filter By VORTEX compares lines VI+ and VI−. It allows direction by their current ratio.</mark>

### Add a filter to the task

<mark style="color:$tint;">Open up the task of creating or editing a</mark> [<mark style="color:$tint;">Binance robot</mark>](/en/binance-robot/binance-first-task-and-launch.md) <mark style="color:$tint;">or a Bybit robot. —</mark> [<mark style="color:$tint;">The Bybit robot</mark>](/en/bybit-robot/bybit-first-task-and-launch.md) <mark style="color:$tint;">In the filter block, select VORTEX.</mark>

<mark style="color:$tint;">Field Active is missing. Set the filter for the pair the task is going to work with.</mark>

### Set the calculation

* <mark style="color:$tint;">**The TF**</mark> <mark style="color:$tint;"></mark><mark style="color:$tint;">sets the time frame for the calculation. The initial value is 1 minute.</mark>
* <mark style="color:$tint;">The</mark> <mark style="color:$tint;"></mark><mark style="color:$tint;">**Type of candle**</mark><mark style="color:$tint;">s is either normal or Heiken-Ash. By default, ordinary candles are used.</mark>
* <mark style="color:$tint;">**Calculation**</mark> <mark style="color:$tint;"></mark><mark style="color:$tint;">On closing the bar or On crossing (every second). The first uses closed bars, the second takes into account the current unopened bar. In the new form, the mode P is selected (every second).</mark>
* <mark style="color:$tint;">Period from 2 to 50 bars. The starting value is 14.</mark>

### When the filter allows action

* <mark style="color:$tint;">VI+ above VI− is the allowed long.</mark>
* <mark style="color:$tint;">VI+ below VI− or equal to it is allowed short.</mark>
* <mark style="color:$tint;">New line intersections are not a separate requirement of this filter.</mark>

### Determine the meaning of the parameters

<mark style="color:$tint;">When you turn on the reverse, the sides change places. The line equation also goes to the opposite side; it doesn't mean the two directions are allowed.</mark>

<mark style="color:$tint;">The directions rules above are for the deactivated Reverse field? is the initial state of the form. If you turn it on, the permissions for the long and short change places. The conditions of both directions and the same direction will remain the same.</mark>

### Set the action when you exit the filter

<mark style="color:$tint;">Field When the filter is out refers to the situation when the task stops passing this condition. The new card has the Cancel Cycles option. The form also includes Sell by market and Sell by market with deviation (if indicated).</mark>

<mark style="color:$tint;">The filter can also affect a task that is already working: the exit from the condition transmits the selected command. Before you save, check the command's implications for your robot in the Binance or Bybit task description. —</mark> [<mark style="color:$tint;">Binance tasks</mark>](/en/binance-robot/binance-robot-tasks-and-active-trades.md) <mark style="color:$tint;">—</mark> [<mark style="color:$tint;">Bybit tasks</mark>](/en/bybit-robot/bybit-robot-tasks.md)

### Save and verify the task

<mark style="color:$tint;">Save the filter card, then check the rest of the conditions and parameters. Several filters should allow it to move at the same time. The filtering permission itself does not mean that the order has been sent or executed.</mark>

<mark style="color:$tint;">If the task mode supports the task without a basic signal, the filters can be involved in its start. So the conditions and the action you choose to take when you exit them should be checked before the robot starts.</mark>
