CRYSTAL UNIVERSAL BUFFER COPY EA
The Most Powerful Universal Trading Robot for MetaTrader 4
8 Built-in Strategies. Unlimited Custom Indicators. One Professional EA.
Why buy a new EA every month? Buy this once - and trade ANY strategy, ANY indicator, ANY market.
WHAT MAKES THIS EA DIFFERENT
Most trading robots in the market are locked to one strategy. When the market changes - or you discover a better indicator - you have to buy a new EA. Spend money. Configure again. Test again.
Crystal Universal Buffer Copy EA breaks that limitation forever.
Inside this single EA, you get 8 ready-to-trade built-in strategies using the most popular technical indicators in the world. AND - if you have your own favorite indicator (paid or free, from MQL5 Market or anywhere else) - this EA will automatically read its signal buffers and trade them for you.
Truly universal. Truly plug-and-play. Truly one-time investment.
One EA. Eight Strategies. Unlimited Possibilities.

STRATEGY LOGIC EXPLAINED
1. MA Crossover (Default)
Classic trend-following strategy. Fast MA crosses above Slow MA - BUY. Fast MA crosses below Slow MA - SELL. Configurable Fast period, Slow period, and MA method (SMA, EMA, SMMA, LWMA).
2. RSI Reversal
Mean reversion strategy. RSI exits the oversold zone (default 30) - BUY. RSI exits the overbought zone (default 70) - SELL. Catches reversals with precision.
3. Stochastic Cross
Momentum strategy. K-line crosses above D-line in oversold zone - BUY. K crosses below D in overbought zone - SELL. Configurable K, D, slowing, OB and OS levels.
4. MACD Cross
Momentum plus trend filter. MACD crosses above signal AND above zero - BUY. MACD crosses below signal AND below zero - SELL. Strong trend confirmation built in.
5. Bollinger Bands
Volatility-based reversion. Price exits below lower band and re-enters - BUY. Price exits above upper band and re-enters - SELL. Configurable period and deviations.
6. ADX Trend
Trades only in strong trends. ADX must be above threshold (default 25). Then plus DI crosses minus DI for entries. Filters out choppy markets automatically.
7. CCI Reversal
Quick reversal detector. CCI crosses above oversold (default minus 100) - BUY. CCI crosses below overbought (default plus 100) - SELL. Great for scalping setups.
8. Ichimoku Cloud
Comprehensive trend system. Tenkan crosses above Kijun AND price above cloud - BUY. Tenkan crosses below Kijun AND price below cloud - SELL. The full Ichimoku trading method.
UNIVERSAL CUSTOM INDICATOR MODE
This is where the EA becomes truly limitless.
Switch to Custom iCustom Mode and the EA can read signals from ANY indicator that exposes signal buffers - paid, free, marketplace, custom-coded, anything.
4 Detection Modes Cover Every Indicator Style
| Mode | Logic | Example Indicators |
|---|---|---|
| Non-Empty | Buffer not equal to EMPTY and not zero | Crystal HA Signals, arrow indicators |
| Equal | Buffer equals threshold | Flag indicators (1.0 BUY, minus 1.0 SELL) |
| Greater Than | Buffer greater than threshold | RSI greater than 70, MACD greater than 0 |
| Less Than | Buffer less than threshold | RSI less than 30, MACD less than 0 |
If your indicator outputs signals to a buffer - this EA can trade it.

FREQUENTLY ASKED QUESTIONS
Q: Will it work with my paid indicator?
If your indicator outputs signals through buffers (most do), then yes - just set Custom Mode and provide the indicator name and buffer indexes.
Q: Do I need any extra software or service?
No. The EA is fully self-contained. The 8 built-in strategies use native MetaTrader functions and require nothing extra.
Q: Can I use it on multiple charts at the same time?
Yes. Use different magic numbers per chart. They will not interfere with each other.
Q: Does it work in Strategy Tester?
Yes, fully. The EA auto-detects the tester and optimizes visuals. Built-in strategies need no extra setup. For custom mode, place the indicator in the tester indicators folder.
Q: Which strategy is the most profitable?
Depends on the market. MA Crossover for trends, RSI Reversal for ranges, ADX Trend for strong moves. Test all 8 on demo and find what works for your market.
Q: What if the indicator I want to use is not free?
The EA does not include or distribute any third-party indicators. You must own the indicator separately. The EA simply reads its public buffer values via standard iCustom.
Q: Can I run multiple strategies simultaneously?
Yes. Open multiple charts. One EA per chart. Each with a different strategy and unique magic number. Run all of them at once.
Q: Is there a refund policy?
MQL5 Market has its own policies. The product includes free demo via the rental option to test before purchase.
