Risk Management During News Events

News and event risk, the sharp, unpredictable moves that come from data releases, central bank speeches, or sudden political shocks, is one of the toughest things to plan around. But it's not something you can avoid.

The traders who last are the ones who prepare for it, not the ones who get caught off guard by it. That's what this lesson is about: spotting the risk before it hits, and knowing exactly how to handle it once it does.

Determining Appropriate Position Sizing

That part trips up almost everyone when they first start out. Position sizing isn't just picking a random number of lots and hoping for the best, it's actually simple math once you know the formula.

Decide how much of your account you're willing to risk on any single trade (usually 1-2%), then work backward from your stop-loss distance to figure out how big your position should be.

The formula looks like this:

• Risk % ÷ Stop-loss distance (%) = a multiplier.

• Multiplier × Account size = Your position size.

Let's walk through it with real numbers, so it actually clicks.

In every case, the tighter your stop-loss, the bigger your position size needs to be to still hit your target risk amount.

And the wider your stop, the smaller your position gets. The dollar risk stays exactly the same either way, only the position size changes to match it.

A few things worth remembering:

• Your stop-loss placement will be different on every trade, so your position size will be too. There's no fixed number that works every time.

• Don't skip the math and just "eyeball" your position size, that's how people blow past their real risk without realizing it.

• The exact decimals don't need to be perfect. Rounding your multiplier is fine, close enough gets the job done.

How much should you actually risk per trade?

• 1% risk: safer, but growing your account will be slower.

• 2% risk: faster growth, but drawdowns hit harder.

• Sweet spot: somewhere in between, unless your strategy has a genuinely high win rate, in which case going slightly higher can make sense.

Position sizing isn't guesswork, it's just a bit of math that keeps every trade, win or lose, within limits you can actually live with.

Effective Use of Stop Loss and Take Profit

Getting into a trade is only half the job. What really separates good traders from the rest is how they handle the trade once they're in it, and that starts with using your stop-loss the right way.

Stop-loss is an order that protects you from big losses. You already know roughly half your trades are going to lose, that's just how trading works.

A stop-loss makes sure that when a trade goes wrong, you get out with a small, planned loss instead of watching it turn into a disaster.

3 ways to use your stop-loss:

2 mistakes to avoid:

Too far away: your risk-reward shrinks, and you're not making much even on a win

Too close: small wicks and normal price noise stop you out, even when you were right about the trade

The fix: place your stop at the point that actually invalidates your trade, not just a random distance away.

If you're buying, that usually means just under the swing low. If that level breaks, the trend has likely flipped, and you don't want to be in the trade anyway.

Trailing your stop for bigger profits

Once a trade is working in your favor, you can trail your stop behind the market structure, moving it up to just above each new lower high as price makes new lows.

This locks in profit step by step instead of risking it all on hitting your final target.

A more aggressive version: once you're already sitting on solid profit (say, 3% or more), you can trail your stop candle by candle, placing it above the previous candle each time a new one forms in your favor.

This won't catch every last pip of a move, but it protects you from turning a strong win into a loss if the market suddenly flips.

Research backs this up, too. A study looking at nearly a century of market data (1926–2020) found that a simple trailing stop-loss rule, selling once a position dropped 15-20% from its peak, cut the worst portfolio loss from 62% all the way down to 26%.

That's not a small difference. It's the gap between a portfolio that recovers and one that takes years to.

Managing Slippage and Unexpected Volatility

Slippage is one of those hidden costs traders forget about, but it adds up more than you'd think.

It is the gap between the price you place your order at and the price you actually get filled at. If you buy something trading at $28.22 and end up filled at $28.32, that's 10 cents of slippage. Same idea applies to forex or anything else.

Most traders don't notice it because the trading blotter just shows the fill price, and that becomes your new "anchor point".

So slippage quietly slips by unnoticed, but over time, especially if you trade a lot, it can seriously eat into your profit.

5 ways to reduce slippage

Stops and slippage on the way out

Most people worry about slippage going into a trade, but a lot of it actually happens on the way out, especially with stop orders.

A stop order is really just a trigger: once price hits your level, it fires off a market order. And a market order, by definition, can slip.

• Fix option 1: Use a stop-limit order instead. It fires a limit order instead of a market order once triggered, capping your worst-case fill, but you risk not getting filled at all if price runs past your limit.

• Fix option 2: Break your exit into chunks instead of trying to get out all at once at a single price.

• Fix option 3: Avoid placing stops during the riskiest windows, like market open or major news releases, if you're able to accept the extra risk of staying in the trade a little longer instead.

The most famous example of this: the 2015 Swiss Franc shock. In January 2015, the Swiss National Bank suddenly removed a currency floor it had defended for over three years.

Within minutes, EUR/CHF collapsed from around 1.20 to below 1.00, and in some cases traders weren't filled anywhere near their stop-loss level because there simply weren't buyers at any price in between. Some accounts even ended up negative, owing more money than they had deposited.

It's the extreme end of what can happen when a stop order can't find a fair price to fill at.

Key Takeaways

• Position sizing is just math, risk 1-2% per trade, and let your stop-loss distance decide your position size.

• Stop-losses do more than limit damage, a simple trailing rule cut historic losses from 62% to 26%.

• Slippage is real: in 2015, EUR/CHF crashed from 1.20 to below 1.00 in minutes.
