Playing the Federal Reserve meetings.
8 times à year, the US Federal Reserve (Central Bank, the FED) has its ‘regular‘ meetings to address the state of the US economy and its interest rates policy.
In conjuction to a FED meeting, there are great price fluctuations in the financial markets as shown through the charts below. These variations are extra ordinary trading opportunities intraday and very short term. The cause of a certain price move is extremely difficult to foresee or "know" in advance. Market behaviour statistics may lead traders to 'a right path' to find potential profits from certain patterns. Remember that market participants always trade price to profit and nothing else.
Gold and the Nasdaq100 index are great examples of how price movements evolve through important FED meetings.
Below is Gold‘s behavior over 3 meetings (August, September, and November of 2018). The chart displays the period from ‘just before the US open the day prior to the FED meeting to just after the European opening bell two days after the meeting’. The price of Gold tanks USD 55 over the three meetings. The interesting aspect is to observe how similar the trading patterns are at all 3 events.

Below is how the Nasdaq100 index behavior acts over the same 3 meetings (August, September, and November of 2018).
The chart displays the period from ‘just before the US open the day prior to the FED meeting to just after the European opening bell two days post the meeting’. The Nasdaq100 gains 200 points over the 3 meetings.

In conjuction to price movements at these type of events, it is essential for short term trades to be prepeared with a suitable stop loss. If not great wins, a respectable stop-loss will minimize losses.
