Non Bias 'Straddle' Trading the economic calendar advice & tips please?

Hi all, I’m going to look in to the Non Bias ‘Straddle’ Trading the economic calendar strategy as per one of Babypips lessons.

Are there any traders out there who have tried this or have any tips/advice ?

It seems like brokers massively increase spreads shortly before economic events… I wonder if that makes the strategy unworkable?

Any techniques etc that you use or are aware of?

Many thanks in advance.

The are some strategies based on placing orders above and below the current price just before the event. At the same time, the price movement should be substancial, otherwise small movement with tetracement would cause loss. Of course, the two opposite orders would cover one another, but the size of loss would be the distance between orders.
So, such strategies work best on the volatile markets and could create a series of losses during range movement.
