USDX Trader EA - Trade the US Dollar Index even if your broker does not include the USDX among their symbols. - expert for MetaTrader 5

USDX Trader v1.30 — Synthetic Dollar Index chart and basket trading for MetaTrader 5

Version 1.30 · MetaTrader 5 · Any broker that offers the major USD pairs

USDX Trader builds a synthetic US Dollar Index from the currency pairs already in your Market Watch, shows it on your chart as a normal symbol, and lets you buy or sell the index as a basket of the underlying pairs — with take-profit and stop-loss measured on the index itself, not on any single pair.

It is made for traders whose broker does not offer a USDX / DXY symbol.

Why this matters if your broker does not offer USDX

The US Dollar Index is the standard yardstick for broad dollar strength. Many retail brokers do not list it at all, or list only a futures-based CFD with wide spreads, limited hours or contract rolls. Without it, traders often have to watch the index on a separate website and trade on another platform.

Important: this is a replication of the index from spot pairs, not the official ICE data feed. Expect small differences from the published index (see Limitations).

Key features

• Synthetic USDX on your chart. Attach the EA to any chart. It switches the chart to the synthetic symbol and switches back when you remove the EA.
• Preset dropdown. USDX, two broad-dollar baskets, an equal-weight basket, or your own custom combination.
• Basket trading. BUY / SELL / CLOSE from the on-chart panel. Leg sizes follow the index weights.
• Virtual TP and SL in index points. Set 0 for no TP or no SL.
• TP/SL levels on the chart before entry (projected for BUY and SELL) and after entry (live lines).
• Adjustable size with + / − buttons and an editable field. A plan table shows each leg's lots before you trade.
• Minimum-lot protection. A leg below the broker's minimum lot is rounded up to the smallest allowed size, and you must confirm before the trade is placed.
• Last N bars rebuilt from real ticks of all legs for accurate highs and lows on the bars you see.
• Strategy Tester support with an optional automatic mode (see below).

How the index is calculated

The USDX preset uses the ICE US Dollar Index formula:

USDX = 50.14348112 × EURUSD^-0.576 × USDJPY^0.136 × GBPUSD^-0.119 × USDCAD^0.091 × USDSEK^0.042 × USDCHF^0.036

Buying USDX = buy USDJPY, USDCAD, USDSEK, USDCHF and sell EURUSD, GBPUSD. Selling USDX is the reverse.

The chart shows the index bid. Opening a long basket costs the index ask, built from the correct bid or ask of each leg, so spreads are included in entry and exit levels.

Presets

The broad presets are approximations of published broad-dollar indices, not replicas. Their absolute level is scaled to read about 100 and has no official meaning.

Custom example: EURUSD:1;GBPUSD:-1 with the geometric formula gives the EURGBP ratio.

Lot sizing

For the geometric formula, each leg's exposure is weight × size × Basket unit in account currency and is converted to lots with the symbol's tick value. With the default basket unit of 100,000, size 1.0 ≈ 100,000 of exposure, and a 1% move in the index is worth about 1,000 in account currency.

Small legs (SEK, CHF, SGD) need a larger size to stay accurate. If a leg's ideal volume is below the broker's minimum lot, the EA uses the minimum lot, shows the ideal and actual volumes and the percentage difference, and asks for your confirmation. The basket will then not match the target weights exactly.

Strategy Tester and automatic mode

Custom symbols cannot be created in the Strategy Tester, so in the tester the EA computes the index virtually from the leg symbols (it selects them automatically). In the tester there are no dialogs and no panel clicks, so an optional automatic mode is provided:

The automatic logic is a simple demonstration: fast/slow EMA crossover on closed index bars (default H1, 12/26). It takes a first position after the warm-up and reverses on each crossover, using the virtual TP/SL. It is not an optimised or recommended strategy.

If a leg symbol is missing in the tester, the EA drops it and renormalises the remaining weights so the test can run.

Setup

1. Add every leg of your chosen preset to Market Watch (right-click Market Watch → Symbols).
2. Enable Algo Trading and allow trading in the EA's properties.
3. Drag the EA onto any chart and choose the preset. The chart switches to the synthetic symbol.
4. Check the plan table, set size, TP and SL, then use BUY / SELL.

Run the EA on one chart per instrument, each with its own magic number.

Limitations

• Not the official index. Values come from your broker's prices. Expect small differences from the published ICE index and from DX futures (feed, spread, futures basis, bid vs mid).
• High and low of older bars are approximations. Only the last N bars (default 20) are rebuilt from real ticks; older history is built from M1 bars.
• Multi-leg execution. Each leg pays spread, may be slippage-affected and carries its own swap. A leg that fails to open triggers a rollback of the other legs.
• Virtual TP/SL. Levels are checked by the EA while it is running. If the terminal is offline or the connection is lost, nothing closes the basket. There are no server-side SL/TP orders.
• Gaps and fast markets can fill beyond the TP/SL level.
• One basket at a time per magic number. On netting accounts, other positions in the same pairs will merge with the basket's legs.
• Small sizes distort the hedge ratio because of minimum lot sizes.
• The synthetic symbol is not tradable directly (trading on it is disabled); trades are placed on the underlying pairs.
• The automatic mode is a demonstration and is not optimised.
