This information explains methods to set up, configure, and use Crystal Copycat ULTIMATE v4.50 on MetaTrader 5. It’s written for cash managers, prop-firm merchants, sign suppliers, and superior retail customers who want a native, quick, and dependable commerce copier on a single PC/VPS. The copier helps one MASTER sending trades to as much as 10 SLAVES.
1) What the Copier Does (in a single minute)
You run a minimum of two MT5 terminals on the similar pc/VPS.
One terminal is MASTER (supply). Different terminals are SLAVES (receivers).
When a brand new order seems on the MASTER (market or pending), the copier writes a small sign file within the MT5 Frequent folder.
Every SLAVE reads that file and opens/modifies/closes the identical commerce in keeping with your quantity and threat guidelines.
No DLLs, no web API. Every little thing is native and quick.
Tip: “Native” means all MT5 terminals use the similar Home windows person account and share the similar MT5 Frequent folder.
2) Necessities Guidelines
Home windows PC or VPS (secure web; 24/7 for stay use)
MetaTrader 5 (hedging account sort advisable)
All terminals put in below the similar Home windows person
Sufficient free disk area (sign information are tiny)
You recognize your dealer’s min lot, lot step, cease ranges
Elective: RDP/AnyDesk to handle the VPS remotely
3) Fast Begin (5 steps)
Set up the EA on all terminals (one MASTER + as much as 10 SLAVES). Connect the EA to any chart (H1 or M15 is okay). One chart per terminal is sufficient.
On the MASTER: set Operation Mode = MASTER. Set Variety of Slaves = 1…10 (what number of receivers you’ll use).
On every SLAVE: set Operation Mode = SLAVE and Slave Quantity = 1…10 (every slave has a singular quantity).
Select Quantity Mode on every SLAVE (Fastened, Fairness-ratio, or Threat-percent). If utilizing Threat-percent, set a Default SL (pips) for sizing when the incoming commerce has no SL but.
If symbols differ throughout brokers, fill Image Mapping (e.g., XAUUSD=XAUUSD.r ). Allow Algo Buying and selling and examine the dashboard.
End result: When the MASTER opens or modifies a commerce, the SLAVES comply with inside moments.
4) How Native Communication Works
The MASTER writes commerce data right into a small textual content file contained in the MT5 Frequent folder.
Every SLAVE reads from its personal sign file (e.g., slave1_signals.dat , slave2_signals.dat , … slave10_signals.dat ).
The copier makes use of retry & back-off to deal with temporary file locks (e.g., antivirus or Home windows).
Time-sync ignore possibility helps if terminals present small clock variations.
Computerized cleanup retains information small throughout lengthy periods.
5) Dashboard — What You See On Chart
MASTER
SLAVE
Mode: SLAVE + Slave Quantity
Acquired / Success / Failed counts
Success fee (%)
Present drawdown (%) and threat standing
Default SL (pips) in use (for Threat-percent sizing when wanted)
File warnings (if any)
Elective time-sync standing
If there’s a drawback, the dashboard often reveals why (file busy, min fairness hit, drawdown restrict, image not discovered, and many others.).
6) All Inputs — Abstract
A. Normal
Operation Mode: MASTER or SLAVE (function of this terminal)
Variety of Slaves (MASTER solely): 1–10 (prepares the proper information)
Slave Quantity (SLAVE solely): 1–10 (distinctive per slave)
Magic Quantity (non-compulsory): Inner commerce ID (maintain distinctive if operating different EAs)
Ignore Time Sync (non-compulsory): Avoids warnings if clocks differ somewhat
B. Symbols & Mapping
Image Mapping (non-compulsory): Pairs separated by commas.
Instance: XAUUSD=XAUUSD.r,EURUSD=EURUSD.m,US30=US30.money
Left = MASTER image, Proper = SLAVE image.If empty, the copier tries to detect widespread names. For finest reliability, fill mappings manually.
C. Quantity & Threat
Quantity Mode (select one per SLAVE):
Fastened Lot — Each commerce makes use of your set lot (e.g., 0.10).
Fairness-Ratio — Lot ≈ (Slave Fairness / Grasp Fairness) × Grasp Lot.
Threat-% — Lot from threat % and SL distance. If no SL comes from MASTER, use Default SL (pips) for sizing.
Fastened Lot Dimension (Fastened mode): actual lot per commerce.
Default SL (pips): fallback distance for sizing solely when no SL is supplied.
Max Threat Per Commerce (%): higher cap for every new order (guard towards oversizing).
D. Security Limits (non-compulsory)
Max Drawdown (%): if fairness drawdown is above this degree, the SLAVE pauses new entries.
Min Fairness: if fairness falls beneath this worth, the SLAVE pauses new entries.
Auto Halt/Resume: copier halts on breach and resumes when regular.
E. File I/O & Stability
File Retry Delay (ms): wait time earlier than retrying a busy file.
Max File Retries: what number of retries earlier than warning.
Cleanup Conduct: computerized; no motion required.
F. Show & Logs
7) Quantity Modes — Detailed Examples
7.1 Fastened Lot
You set 0.10 on the SLAVE.
MASTER opens 1.00 on Gold → SLAVE nonetheless opens 0.10.
Easy, regular threat. Good for evaluations or strict lot insurance policies.
When: You need the identical lot each time.
Tip: On unstable symbols (Gold, Indices, Crypto), begin small (e.g., 0.05–0.20).
7.2 Fairness-Ratio
Formulation: Slave Lot ≈ (Slave Fairness / Grasp Fairness) × Grasp Lot.
Instance: Grasp Fairness 5,000 opens 1.00; Slave Fairness 1,000 → ratio 0.20 → Slave opens ~0.20.
Threat stays proportional throughout totally different account sizes.
When: You need constant threat throughout many accounts.
Tip: Recheck after deposits/withdrawals; affirm dealer permits micro-lots.
7.3 Threat-%
You select threat % per commerce (e.g., 1%).
SLAVE calculates lots so a full SL loss ≈ your chosen % of fairness.
If the incoming sign has no SL, SLAVE makes use of Default SL (pips) to dimension the lot.
Instance: Fairness 2,000; threat 1% → $20 threat; efficient SL 100 pips → lot sized so 100 pips ≈ $20.
When: Funded accounts, disciplined sizing, unstable symbols.
Vital:Default SL is solely for sizing when no SL is shipped; it doesn’t place a cease.
If MASTER later modifications SL/TP, already-open lot dimension doesn’t change.
Pending orders with out SL use Default SL at execution time.
8) Security Limits — How They Shield You
Max Drawdown (%):
If above your restrict, new entries are paused; current trades keep open.
When drawdown is again beneath the restrict, copier can auto-resume.
Use case: Prop agency each day loss is 5% → set 4.0–4.5% for a buffer.
Min Fairness:
If fairness is beneath this degree, new entries are paused.
Prevents over-trading when fairness is low / margin is tight.
Max Threat Per Commerce (%):
Default SL (pips):
Auto Halt/Resume:
On any breach, copier prints a transparent motive and pauses entries.
Resumes routinely when regular.

C) Funded Account (Strict Each day Loss)
Quantity: Threat-percent (0.3–0.8% typical)
Default SL: practical for the image
Max Drawdown: barely beneath agency rule
Min Fairness: security line to keep away from margin strain
Verbosity: low (clear logs)
D) Excessive-Volatility Symbols (Gold/Indices/Crypto)
Begin small on Fastened Lot or use Threat-percent
Default SL bigger than for majors
Watch dealer stop-levels and min lot dimension
12) Actual-World Walkthroughs
Pending with out SL
MASTER locations a Purchase Cease on XAUUSD with out SL/TP.
SLAVE in Threat-percent mode makes use of Default SL to dimension the lot when the order triggers.
If MASTER provides SL/TP later, SLAVE updates SL/TP; lot dimension stays the identical.
Shut-All on MASTER
Dealer Suffix Distinction
MASTER makes use of XAUUSD , SLAVE dealer makes use of XAUUSD.r .
Set XAUUSD=XAUUSD.r and add XAUUSD.r to Market Watch.

Exclude the MT5 Frequent folder from antivirus real-time scanning if allowed.
If “file busy” warnings seem, enhance File Retry Delay and Max File Retries.
Don’t run two totally different copiers on the identical chart.
Use one MASTER per supply account.
14) Testing Safely Earlier than Dwell
Use demo first; run each MASTER and SLAVE on the identical VPS.
Begin with small sizes (Fastened Lot 0.01–0.05) and fundamental symbols (EURUSD).
Check market orders, pending orders, SL/TP modifications, partial closes, and close-all.
Affirm success fee >99% with no persistent warnings.
15) Troubleshooting (Fast Solutions)
No trades on SLAVE: Examine Mode, Slave Quantity, mapping, and Market Watch.

File busy warnings: Enhance retry delay and retries; contemplate antivirus exclusion.
Hit drawdown/min-equity: Copier pauses by design; look ahead to restoration or modify limits.
Totally different symbols: Fill Image Mapping exactly.
