Triggers
Triggers are the deviation of the analysts median forecast from the actual numbers.
For the May 2017 Great Britain month over month Core Retail Sales numbers, the median forecast was -0.5%.
The triggers for the report were set to:
| S1 | S2 | S3 | B1 | B2 | B3 | |
| -0.7 | -1.2 | -1.7 | 0.7 | 1.2 | 1.7 |
That means any deviation of 0.7 or higher would trigger the BUY1 Action. Any negative deviation of -0.7 or lower would trigger the SELL1 Action. Any deviation of 1.2 or higher would trigger the BUY2 action.
When this actual numbers came out at -1.2%, it instantaneously triggered the SELL2 action on the FX BOLT application.
The worse than expected number lead to a hard sell-off of the GBP/USD.
