Hedging News Until Margin Call

Hi Guys,
Been inactive for a while from this forum but still trading in real life.
Today I just got like a sudden dumb but fun ideas to trade, I think this will not work but my other self says really loud in my mind that this is how to safely bet on the market. I really want to hear your opinion.
The Idea,
Start with two different broker trading account, let's say Broker A and B. To this broker you put small amount of money that you're okay to lose. Let's say $100.
Then, precisely 1 minute before big news event you go Long on broker A with full margin and go Short on broker B with full margin.
I think this only works on Indices and Stocks as they tend to move in one direction on news and doesn't really have lot of whiplash.
Scenario 1 the market goes like 1% up, broker A will profit substantially perhaps tripling your account. broker B will got liquidated all of your $100 and that's it since you don't put any other money in this account.
Scenario 2 is the other way around from scenario 1.

This way you can safely protect your capital from sudden price move and margin call.

Let me know your opinion on this or perhaps you have heard something similar. Or you have another ideas that dumber than this one, let me know.

Markets often do not behave predictably during big news events, especially with highly leveraged positions. There's potential for slippage and whipsaws, even with full margin. For example, if news causes a sudden initial spike in one direction followed by a correction, both positions could be quickly affected.

Sometimes this work though, and sometimes there are news event that can able to liquidate upper/bottom area where there are SL's, but yeah 2 out of 5 of news event don't target the SL and came up/down sharply

Yea, but in the last 3 years i mainly trade indices and as far as what i wrote in my note on each news event, the whiplash are quite small compared to forex market. And on indices, once the news released, price will hold on that area for quite long before making new hi/low.

Yea, worst case scenario is the news doesn't shake the market a lot which make the movement only enough to cover the loss on other broker but not making any profits.
