Reject trading signals

Time filters allow traders to accept or reject trading signals depending on when they appear. By adding one or more time filters the trader can manage his signals AND position based on time. The possibilities are endless. For example reject signals during the opening phase of a trading session, the five minutes before and after important statistics are announced and during a deadzone such as lunch time.

These are the advantages of time filters:

  • Choice of time filters with different functions (flat, bloc).
  • Filters types can be combined.
  • Filters can be easily switched on/off.
  • No programming required.

Let’s look at a simple example which is not uncommon. A trader may want...

  1. To not open any new position 20 minutes before the market close, and
  2. to close any remaining open positions 5 minutes before the market close, thereby avoiding overnight positions.

These requirements can be automatically managed by the NanoTrader. They require no coding or programming. In the example the trader would use a block filter and a flat filter.


These two types of time filters each have their own logic.

Flat ensures that an open position is closed and that new entry signals are ignored.

Block ensures that open positions remain open until an exit signal occurs, but entry signals are ignored.

Block and flat periods are visible in the charts.

This example shows the filter settings for the trader who does not want to open any new positions 20 minutes before the market close and who wants to close any open position 5 minutes before the market close.

Reject signals from a trading strategy. Trade only during defined time periods.

The time filters can be activated or deactivated by simply (un)ticking them.

CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 66% of retail investor accounts lose money when trading CFDs with this provider. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

Futures are complex instruments subject to unpredictable changes in price. They are financial instruments which offer the investor the possibility to use leverage. The use of leverage implies the risk of losing more than the total value of the account.

Investments in digital assets are considered highly speculative investments and are subject to high volatility and therefore may not be suitable for all investors.
