Your EA has a information filter. Good transfer. It is set to cease buying and selling Half-hour earlier than and after high-impact information.
So why did you continue to lose cash throughout NFP final Friday?
This is the factor no person tells you about information occasions: The issue is not your EA buying and selling throughout information. The issue is what occurs to the market infrastructure when everybody else panics.
The Hidden Information Buying and selling Disasters No one Talks About
Let me break down what truly occurs throughout a serious information launch:
T-minus 5 seconds: Spreads begin widening. Your typical 0.8 pip EURUSD unfold? Now it is 3 pips. Your EA is not buying and selling, however that present place you’ve gotten? Its cease loss simply grew to become dearer.
T-0 (Information hits): Spreads explode to 10-20 pips. Liquidity vanishes. The order e book seems like Swiss cheese – enormous gaps between bid and ask costs.
T+2 seconds: Value spikes 50 pips in a single course, then 70 pips in the wrong way. Your “protected” cease loss? It simply obtained executed 25 pips away from the place you set it.
T+30 seconds: Issues relax. Spreads normalize. Your EA’s information filter did its job completely. However you are still down $500 on a place that was opened two hours in the past.
Your information filter prevented new trades. Nice. Nevertheless it did not shield you from what information does to your present positions.
The Three Sorts of Information Injury (And Solely One Will get Filtered)
Kind 1: Direct Buying and selling Injury (What Everybody Is aware of)
That is what your information filter prevents:
- EA opens commerce proper earlier than information
- Huge volatility hits
- Cease loss will get destroyed
- Account suffers
Your filter blocks this. You are good right here.
Kind 2: Collateral Injury (The Silent Killer)
That is what most merchants miss:
- You’ve got positions open from earlier
- Information hits, spreads widen dramatically
- Your worthwhile commerce hits cease loss attributable to unfold alone
- Or worse: slippage in your cease loss prices you an additional 20 pips
Your information filter? Utterly ineffective towards this.
Kind 3: Put up-Information Aftershocks (The Alternative Thief)
This occurs 5-Half-hour after information:
- Market finds new equilibrium
- Good setups seem in every single place
- Your EA continues to be in “information lockdown”
- You miss one of the best trades of the day
Your conservative 30-minute buffer simply price you the restoration trades.
The Actual Option to Configure Information Filters (Not What the Handbook Says)
Neglect the generic “cease buying and selling Half-hour earlier than/after” recommendation. This is what truly works:
1. The Graduated Response System
Not all information is created equal. Your filter should not deal with them the identical:
Excessive Impression (NFP, Central Financial institution Selections, CPI):
- Cease NEW trades: quarter-hour earlier than
- Shut present trades: If revenue > 10 pips, shut 5 minutes earlier than
- Resume buying and selling: 10 minutes after (not 30!)
- Particular rule: Widen stops on present positions to 1.5x regular
Medium Impression (GDP, Retail Gross sales, Employment):
- Cease NEW trades: 5 minutes earlier than
- Present trades: Go away them alone however monitor
- Resume buying and selling: 5 minutes after
- No cease adjustment wanted
Low Impression (Housing knowledge, Minor indicators):
- No filter wanted
- Possibly improve cease by 2-3 pips
- Enterprise as typical
2. The Forex Pair Intelligence
This is what most EA builders will not let you know: Not all pairs react equally to information.
USD Information (NFP, FOMC, CPI):
- EURUSD: Goes completely loopy – full safety wanted
- GBPUSD: Wild however predictable – average safety
- USDJPY: Is dependent upon danger sentiment – watch fairness markets
- AUDUSD: Typically strikes reverse to logic – be additional cautious
EUR Information (ECB, EU CPI):
- EURUSD: Clearly vital
- EURGBP: Typically extra unstable than EURUSD!
- EURJPY: Multiplied volatility – hazard zone
The Good Play: Configure your information filter PER PAIR, not globally.
3. The Unfold Monitor Addition
Your information filter wants a diffusion filter companion. This is my setup:
Regular unfold EURUSD: 0.8 pips If unfold > 2 pips: No new trades If unfold > 5 pips: Contemplate closing worthwhile positions If unfold > 10 pips: Emergency mode – widen all stops
This protects you even when your information calendar fails to replace (sure, it occurs).
My Precise Information Filter Configuration
After years of testing, this is precisely how I configure information filters:
The Pre-Information Guidelines
60 minutes earlier than high-impact information:
- Examine all open positions
- Shut something below 5 pips revenue
- Transfer stops to breakeven on all the pieces else
quarter-hour earlier than:
- No new trades allowed
- Present positions get stops widened by 50%
- Trailing stops disabled briefly
5 minutes earlier than:
- Shut any positions within the affected foreign money if worthwhile
- Remaining cease adjustment to 2x regular distance
- Allow “panic button” monitoring
The Throughout-Information Protocol
Throughout the occasion:
- Monitor spreads like a hawk
- If spreads exceed 10 pips, put together to shut all the pieces
- Look ahead to “cease looking” candles
- Do NOT attempt to commerce the spike (critically, do not)
The Put up-Information Restoration
5 minutes after:
- Examine if preliminary volatility has subsided
- Spreads again to < 2 pips? Contemplate re-entering
- Search for fade trades towards the preliminary spike
10 minutes after:
- Regular buying and selling can resume IF:
- Spreads are regular
- No secondary bulletins pending
- Value has discovered a variety
Half-hour after:
- Full regular operations
- Typically one of the best setups seem right here
- Market has digested the information
The Information Occasions That Broke My Filters (Be taught From My Ache)
Swiss Nationwide Financial institution 2015:
My information filter was good. Did not matter. EURCHF moved 2000 pips in seconds. Lesson: Some occasions are past any filter.
Flash Crash 2019 (USDJPY):
No information scheduled. Apple warned on earnings. Yen pairs went insane. Lesson: Not all volatility comes from financial calendars.
COVID March 2020:
Daily was principally NFP-level volatility. Lesson: Throughout disaster, your information filter is ineffective. Simply cut back place sizes.
UK Funds Bulletins:
Not marked as “excessive impression” however GBP pairs go psychological. Lesson: Know your country-specific occasions that calendars miss.
Constructing Your Personal Good Information Filter
As a substitute of counting on default settings, this is how you can construct a filter that really works:
Step 1: Information Assortment
Monitor for one month:
- Each information occasion and its precise impression on YOUR pairs
- Unfold conduct earlier than/throughout/after
- How lengthy volatility truly lasted
- Your EA’s efficiency round these occasions
Step 2: Customized Categorization
Create your individual impression scores:
- Nuclear: Shut all the pieces (Central banks, NFP)
- Excessive: Cease new trades, shield present (CPI, GDP)
- Medium: Improve warning (Retail gross sales, PMI)
- Low: Enterprise as typical (Housing, Client confidence)
Step 3: Pair-Particular Guidelines
Every pair will get its personal profile:
- EURUSD: Most delicate to US information
- GBPJPY: Multiply any volatility by 2
- AUDNZD: Typically ignores information fully
Step 4: The Escape Hatch
At all times have an emergency exit:
- If unfold > 10x regular: Shut all the pieces
- If volatility > 5x ATR: Shut down for the session
- If technical glitch: Have pending orders as backup
Frequent Information Filter Errors That Nonetheless Value Me Cash
Mistake 1: Trusting the Calendar Utterly
- Financial calendars have errors
- Instances change, impression ranges unsuitable
- Answer: At all times have unfold filter as backup
Mistake 2: Identical Filter for All Pairs
- EURUSD wants completely different settings than NZDJPY
- Main pairs ≠ Cross pairs ≠ Exotics
- Answer: Customise per pair primarily based on YOUR knowledge
Mistake 3: Forgetting About Correlations
- You filtered EURUSD for ECB
- However forgot EURJPY can also be operating
- Each get hit, double loss
- Answer: Filter all correlated pairs collectively
Mistake 4: The “Buffer Zone” Entice
- Half-hour earlier than/after sounds protected
- Miss all of the post-news alternative trades
- Overly conservative = misplaced earnings
- Answer: Graduated re-entry primarily based on unfold normalization
The Different: Information Buying and selling Integration
This is a controversial opinion: As a substitute of avoiding information, what in case your EA may use it?
A few of my greatest trades come from:
- Put up-news reversals (fade the spike)
- Continuation patterns after digestion
- Vary breakouts as soon as volatility settles
The secret’s not IF to commerce round information, however HOW:
- By no means commerce the preliminary spike
- Look forward to the primary reversal
- Enter on the second push (with tight cease)
- Take revenue shortly
However that is superior stuff. Grasp the defensive filter first.

The Backside Line on Information Filters
A information filter is not a checkbox characteristic. It isn’t “set and neglect.” It is an lively protection system that wants customization, monitoring, and fixed refinement.
The default “cease Half-hour earlier than/after” is like sporting a raincoat in a hurricane. Higher than nothing, however you are still getting moist.
My present setup has 47 completely different guidelines throughout 8 foreign money pairs. Overkill? Possibly. However I have never had a news-related catastrophe in 2 years.
The market does not care that your EA has a information filter. It cares about how good that filter is.
Make yours smarter.
