Real broker feeds, however, contain microsecond-level volatility bursts that can prematurely trigger tight Stop Losses or dynamic Trailing Stops. + +In our production validation of Jump 10 Index: +- **`OPEN_PRICES`**: Signals and trailing stops only evaluate at candle close. This produces theoretical backtest profits without intrabar stopouts. +- **`REAL_TICKS` / MT5 "Every tick based on real ticks"**: Micro-spikes continuously hit trailing stops intrabar. This reduces realized profits to ~30% of open-price theoretical metrics, but reflects 100% genuine live trading dynamics. + +#### C++ Zero-Copy Execution Architecture +1. **$O(N)$ Two-Pointer Grouping**: Broker ticks are aligned with OHLC candle timestamps in linear time in C++ without incurring Python per-tick overhead. +2. **First-Tick `OnBar()` Triggering**: When a new candle opens, `OnBar()` is invoked on the *very first tick* of that candle. This guarantees that new market orders execute at the true bar open price, while all subsequent intrabar ticks stream through `OrderBook::on_price_update` to manage trailing stops and pending orders. +3. **Sub-Second Throughput**: Replays over 600,000 real broker ticks in **~1.1 seconds**. + +#### Automated Broker Tick Downloader +Use the automated CLI downloader to fetch genuine broker tick data directly from MetaTrader 5: + +```powershell +python backtest_suite/download_broker_ticks.py ` + --symbol "Jump 10 Index" ` + --days 7 ` + --output "backtest_suite/tick_data_cache/jump_10_index_7d_ticks.parquet" +``` + +#### Running Real-Tick Backtests via CLI +```powershell +# Run TrendFinder Leaf using 100% genuine broker ticks +python strategies/trendfinder_leaf/run_backtest.py ` + --symbol "Jump 10 Index" ` + --data "backtest_suite/historical_data_cache/jump_10_index_100k_m5.parquet" ` + --tick-mode REAL_TICKS ` + --ticks-path "backtest_suite/tick_data_cache/jump_10_index_7d_ticks.parquet" +``` + +#### Running Real-Tick Backtests in Python API +```python +import edge_tester as et +import pandas as pd + +# 1.

Overnight Financing & Rollover Swap Mechanics (24/7 vs. Traditional Markets) + +In MetaTrader 5, holding an open position past the end of the trading day incurs an overnight financing cost (or credit) known as **Swap**. `EdgeEngine` strictly replicates MT5's exact daily rollover schedule and financing accounting. + +### Key Rules of the Swap Engine: + +1. **Daily Rollover Timing (00:00 Server Time)**: + - **Naive Mistake**: Many simplistic backtesting scripts mistakenly deduct `swap * volume` on every bar or tick. When testing on M1 or M5 candles, this charges swap hundreds of times per day, completely draining account capital artificially. + - **MT5 Parity**: In `EdgeEngine`, swaps are applied strictly once per elapsed calendar day (`time / 86400`). Holding a trade for 288 M5 bars within the same day incurs zero swap until midnight rollover. + +2. **Floating Swap Accumulation vs. Realized Cash Balance**: + - Accrued swaps do **not** prematurely reduce the cash balance (`account.balance`). + - Instead, swaps accumulate continuously in the position entity's floating swap field (`pos.swap`), reducing floating equity. + - The swap charge is only realized into the cash balance when an exit deal occurs (`DEAL_ENTRY_OUT` or Netting position reduction). + +3. **The 3x Triple Rollover Schedule & Weekend Financing**: + - **Traditional 5-Day Markets (Forex, Metals, Commodities)**: + Traditional currency pairs operate on a **T+2 settlement cycle** (trades settle 2 business days after execution). A position held open from Wednesday to Thursday rolls settlement from Friday to Monday. Because commercial banks and interbank clearing systems are closed over the weekend, **Wednesday night carries a 3x swap multiplier** (covering Wednesday, Saturday, and Sunday), while Saturday and Sunday carry 0 swap. + - Configuration: `spec.swap_rollover3days = 3` (`DAY_WEDNESDAY`). + - **Continuous 24/7 Synthetic Markets (e.g., Deriv Synthetics)**: + Synthetic indices (Volatility, Crash, Boom, Jump) run algorithmically 24 hours a day, 7 days a week, 365 days a year without market closures or weekend bank holidays. + - **Triple swap does NOT apply to Deriv synthetic indices.** + - Swaps are charged flat at $1\times$ every day (including Saturday and Sunday). + - Configuration: `spec.swap_rollover3days = -1` (disables 3x rollover). + - **Cryptocurrency Pairs (BTC, ETH, Altcoins) Across Brokers**: + - **Native Crypto Exchanges (Binance, Bybit, OKX)**: Trade 24/7/365 with continuous 8-hour funding rates. **There is no 3x swap.** + - **Deriv Crypto**: Runs 24/7 with a flat $1\times$ daily rollover (`spec.swap_rollover3days = -1`). + - **Traditional MT5 CFD Brokers (e.g., IC Markets, Pepperstone, Exness, FP Markets)**: + > [!WARNING] + > **Crypto CFDs on Retail Brokers May Incur 3x Swap!** + > Even though cryptocurrency markets run 24/7, many retail MT5 Forex/CFD brokers settle liquidity provider credit lines and fiat currency legs (like USD in BTCUSD) through traditional banking rails that close on weekends. + > Consequently, many brokers configure their MT5 servers with **Friday 3x swap (`swap_rollover3days = 5`)** or **Wednesday 3x swap (`swap_rollover3days = 3`)** for Crypto CFDs! + > Always verify your broker's symbol specification in MT5: `Market Watch` $\to$ Right-click symbol $\to$ `Specification` $\to$ `3-days swap`. + +### Python Symbol Specification Setup + +```python +import edge_tester as et + +spec = et.SymbolSpec() +spec.swap_mode = 2 # 0 = disabled, 1 = points, 2 = currency/money +spec.swap_long = -15.0 # -$15.00 per lot per night for long positions +spec.swap_short = 5.20 # +$5.20 per lot per night for short positions + +# Rollover schedule: +# -1 = Continuous 24/7 (Deriv synthetic indices, native crypto - flat 1x every day) +# 3 = Traditional Forex (3x Wednesday rollover, 0x Saturday/Sunday) +# 5 = CFD Crypto / Indices (3x Friday rollover on traditional retail brokers) +spec.swap_rollover3days = -1 + +cfg = et.TesterConfig() +cfg.enable_swaps = True # Toggle swap accruals during backtests +``` + +--- + +## 9. MT5 Strategy Tester Parity Engine (Order Lifecycle & Accounting) + +EdgeEngine has been reverse-engineered and audited directly against MetaTrader 5's execution binaries (`metatester64.exe` / `terminal64.exe`) to guarantee 100% execution parity. + +### 1. Stop-Limit Orders (`ORDER_TYPE_BUY_STOP_LIMIT` / `ORDER_TYPE_SELL_STOP_LIMIT`) +Unlike standard stop or limit orders, Stop-Limit orders feature two distinct price targets: +1. `price_open` (Stop Trigger Price) +2. `price_stoplimit` (Limit Order Price) + +When market price touches `price_open`, the order is **not** immediately executed at market. Instead, MT5 transitions the order into an active pending Limit Order (`ORDER_TYPE_BUY_LIMIT` / `ORDER_TYPE_SELL_LIMIT`) placed at `price_stoplimit`. `EdgeEngine` emulates this exact two-stage state transition and fires `TRADE_TRANSACTION_ORDER_UPDATE`. + +### 2. Stop-Out Order Book Liquidation & Pending Order Purge +When account equity drops below the broker's Stop-Out threshold (`equity / margin <= stopout_level`): +1. **Pending Order Purge**: MT5 immediately cancels and deletes all active pending orders (`ORDER_STATE_CANCELED`) to release reserved margin before closing any positions. +2. **Loss-Ranked Liquidation**: Active positions are sorted by floating loss, and the position with the greatest loss is closed first (`DEAL_REASON_SO`). If margin level remains below the threshold, subsequent positions are liquidated sequentially until account health is restored. + +### 3. Execution Latency Bypass in Open Prices Mode +In MT5 Strategy Tester, when testing under `TickMode.OPEN_PRICES`, simulated transit delays are automatically bypassed. All bar-open signals execute at the bar opening quote without entering the in-flight latency queue (`in_flight_orders`). This mirrors MT5's speed optimization behavior. + +### 4. Netting Mode Accounting (`ACCOUNT_MARGIN_MODE_RETAIL_NETTING`) +In Netting mode, only one position can exist per symbol: +- **Adding to Position**: Computes the volume-weighted average open price: + $$\text{Open Price}_{\text{new}} = \frac{P_{\text{old}} \cdot V_{\text{old}} + P_{\text{fill}} \cdot V_{\text{fill}}}{V_{\text{old}} + V_{\text{fill}}}$$ +- **Partial Reduction**: Realizes gross profit, exit commission, and pro-rata accumulated swap (`pos.swap * (close_vol / pos.volume)`) directly into the cash balance. +- **Position Reversal**: Fully closes the existing position, realizes all accumulated profit/swap, and opens a new position for the remaining lot volume in the opposite direction (`DEAL_ENTRY_INOUT`). + +### 5. Intrabar SL/TP Resolution Priority (12-Point Synthetic Wave Model) +When testing on bars where both the Stop-Loss and Take-Profit boundaries are touched within the bar range, MT5 resolves priority using the candle's price progression: +- **Bullish Bar (`Close >= Open`)**: Price moves $\text{Open} \to \text{Low} \to \text{High} \to \text{Close}$. For a Buy position, the Low is reached before the High; therefore, **Stop-Loss triggers before Take-Profit**. +- **Bearish Bar (`Close < Open`)**: Price moves $\text{Open} \to \text{High} \to \text{Low} \to \text{Close}$. For a Buy position, the High is reached before the Low; therefore, **Take-Profit triggers before Stop-Loss**. + +--- + +## 10.
