I used MACD-Sample EA to backtest 3 brokers on same USDCHF. Bokers are FXDD, IBFX, NF.
1. Downloaded latest History Data from Alpari History Data Center.
http://www.alpari-idc.com/en/dc/databank.html
2. used Period_Converter script to convert M1 data to remaining timeframes for each Broker.
3. Date Range: 2006.05.17 - 2006.11.24.
4. H1 timeframe & Deposit $3,000.
5. Settings for Backtest
TakeProfit=100
Lots=0.1
TrailingStop=60
MACDOpenLevel=4
MACDCloseLevel=4
MATrendPeriod=25
6. Results.
FXDD Results
Profit- $973.18, MD 4.79%, Profit Trades 28, Loss Trades 5.
FXDD Chart
IBFX Results
Profit- $601.44, MD 8.44%, Profit Trades 25, Loss Trades 6.
IBFX Chart
FN Results
Profit- $937.72, MD 4.76%, Profit Trades 28, Loss Trades 5.
FN Chart
Summary:
FXDD and FN results are virtually the same. IBFX results were off (down) by over 30%. I don't know which Broker's backtest reuslts are closer to forward or live results, but these results should make a concern on which Broker is used when using the MT4 Strategy Tester in EA development and confrimation. Side by Side Demo and LIve results are needed to clarify which Broker's backtest results.
