LT Accelerator Oscillator EA
Complete walkthrough of all inputs for the LT Accelerator Oscillator EA: strategy settings, trade execution, account protection, filters, time schedule, trailing stop, and more.

These inputs define the core trading logic for the Accelerator Oscillator EA. The EA reads the Accelerator Oscillator (AC) - a derivative of the Awesome Oscillator that measures the rate of change of the driving force of the market.
EA Trading Strategy
enumAC_TrendSelects which Accelerator Oscillator strategy the EA uses to generate trade signals.
| Strategy | Signal logic |
|---|---|
| AC_Trend | Buys when AC is positive and rising (green bars above zero); sells when AC is negative and falling (red bars below zero) |
| AC_MiddleLine | Buys when AC crosses above the zero line; sells when AC crosses below zero |
| AC_Color | Buys on two consecutive green AC bars; sells on two consecutive red AC bars |
| AC_Reversal | Buys when AC is below zero and turns green (momentum reversal); sells when AC is above zero and turns red |
Close Trades on Opposite Direction Signal
boolfalseWhen true, a signal in the opposite direction closes any existing position before opening the new one. When false the EA opens the new trade while leaving the existing one open.
Reverse Trade Signal
boolfalseInverts all signals from the Accelerator Oscillator strategy. Buy signals become Sell and vice versa. Useful for testing counter-trend approaches.
Accelerator Oscillator Time Frame
enumPERIOD_CURRENTThe timeframe the EA uses to read Accelerator Oscillator values. PERIOD_CURRENT reads the chart timeframe. Set a higher timeframe to run an AC strategy from H4 or Daily on a lower-timeframe chart.
These inputs define which instrument the EA trades and whether it uses a real or virtual account balance for lot-size calculations.
EA Name
stringLT EAThe internal name displayed on the chart and in log messages. Changing this lets you run two instances of the same EA on the same chart with different settings without naming conflicts.
Type of Symbol
enumNChartSelects whether the EA trades the chart symbol (NChart) or a custom symbol entered in the Trading Symbol field (CChart). Use CChart to trade a different instrument from the one the EA is attached to.
| Option | Behaviour |
|---|---|
| NChart | Trades the chart symbol automatically |
| CChart | Trades the symbol entered in Trading Symbol |
Trading Symbol
stringEURUSDThe symbol the EA will trade when Type of Symbol is set to CChart. Enter the exact symbol name as it appears in your broker's Market Watch (e.g EURUSD, XAUUSD, US30).
Use a Virtual Balance
boolfalseWhen enabled the EA uses the value in EA Virtual Balance for lot-size risk calculations instead of the real account equity. Useful for testing fixed-lot scenarios on a live account without changing real risk.
EA Virtual Balance
int1000The virtual account balance (in account currency) used when Use a Virtual Balance is enabled. Has no effect when Use a Virtual Balance is false.
Core execution parameters: which timeframe the EA reads signals on, trade direction, lot sizing, stop loss and take profit modes, and position management options.
Working timeframe
enumPERIOD_CURRENTThe timeframe the EA uses to read indicator values and generate signals. PERIOD_CURRENT means the EA reads the chart timeframe. Changing this lets you run a higher-timeframe strategy on a lower-timeframe chart.
Trade direction
enumbuy_sellRestricts which side the EA can open. Set to buy to only go long, sell to only go short, or buy_sell to trade both directions.
| Option | Behaviour |
|---|---|
| buy | Opens Buy positions only |
| sell | Opens Sell positions only |
| buy_sell | Opens both Buy and Sell positions |
Search signals on ...
enumbar_1Determines which bar the EA reads for entry signals. bar_1 uses the last fully closed bar (no repainting). bar_0 reads the live forming bar for faster signals at the cost of potential repainting.
bar_1 is the safer default for live trading. bar_0 is useful for scalping strategies where speed matters more than repainting protection.
Money management
enumriskSelects how the EA calculates the lot size for each trade.
| Option | Lot calculation |
|---|---|
| lots_min | Always trades the broker minimum lot |
| lot | Uses the fixed lot size set in Lot Size or Risk in Percentage |
| risk | Calculates lot size so the risk equals the percentage set in Lot Size or Risk in Percentage |
Lot Size or Risk in Percentage
double3.0Interpreted based on the Money management setting. When money management is lot, this is the fixed lot size. When it is risk, this is the percentage of account balance to risk per trade (requires a valid Stop Loss to be set).
Stop Loss Mode
enumSL_FIXEDSelects how the stop loss distance is calculated.
| Mode | Calculation |
|---|---|
| SL_FIXED | Uses the fixed number of points set in Fixed Stop Loss (points) |
| SL_RISK | Calculates a stop distance based on the Risk-Based Stop Loss (% of balance) |
Fixed Stop Loss (points)
uint0The stop loss distance in points when Stop Loss Mode is SL_FIXED. Set to 0 to disable the stop loss entirely. A point is the smallest price increment (e.g. 1 point on EURUSD = 0.00001).
Trading without a stop loss (value 0) exposes the account to unlimited drawdown if the market moves against the position.
Risk-Based Stop Loss (% of balance)
double1.0Active when Stop Loss Mode is SL_RISK. The EA calculates a stop distance such that losing the trade would cost this percentage of the account balance.
Take Profit Mode
enumTP_FIXEDSelects how the take profit distance is calculated.
| Mode | Calculation |
|---|---|
| TP_FIXED | Uses the fixed number of points set in Fixed Take Profit (points) |
| TP_RR | Sets the take profit as a multiple of the stop loss distance |
Fixed Take Profit (points)
uint0The take profit distance in points when Take Profit Mode is TP_FIXED. Set to 0 to disable the take profit.
Risk-Reward Ratio (TP = SL x RR)
double2.0Active when Take Profit Mode is TP_RR. The take profit is set at Stop Loss distance multiplied by this value. A value of 2.0 means the take profit is twice the stop loss distance.
Virtual Levels (hide SL/TP from broker)
boolfalseWhen enabled the EA manages stop loss and take profit internally without sending them to the broker. The broker sees positions with no SL/TP, which can prevent stop hunting on some brokers.
Draw Levels on Chart (requires Virtual Levels)
boolfalseWhen Virtual Levels is enabled and this is true, the EA draws horizontal lines on the chart at the virtual SL and TP levels so you can see them visually.
Only one Position
boolfalseWhen true the EA will not open a new position if one is already open on the symbol. Prevents pyramiding or stacking multiple positions from repeated signals.
Reverse All Trade Signal Combined
boolfalseInverts the final combined signal after all filters are applied. A Buy signal becomes a Sell and vice versa. Useful for testing counter-trend approaches without modifying the strategy logic.
Close opposite of All Trade Signal Combined
booltrueWhen true, receiving a Buy signal will close any open Sell positions (and vice versa) before opening the new position. Keeps the EA from holding conflicting positions simultaneously.
Two-level risk management system. Account Level monitors the overall account and closes positions when drawdown or profit thresholds are reached. Symbol Level does the same but scoped to the current trading symbol only.
Protection based on the account trades
boolfalseMaster switch for Account Level protection. When enabled the EA monitors overall account equity and closes positions automatically when the risk or profit percentage thresholds below are breached.
Total risk % on overall account
double1.0Account Level drawdown threshold. If total open positions are losing more than this percentage of the account balance, the EA triggers the close actions selected below.
Close all Trades (loss)
boolfalseWhen the account loss threshold is hit, close ALL open positions regardless of direction or profit.
Close Only BUY Trades (loss)
boolfalseWhen the account loss threshold is hit, close only Buy positions.
Close Only SELL Trades (loss)
boolfalseWhen the account loss threshold is hit, close only Sell positions.
Close Only Profit Trades (loss trigger)
boolfalseWhen the account loss threshold is hit, close only positions that are currently in profit. Locks in winners while cutting the position count.
Close Only Losing Trades (loss trigger)
boolfalseWhen the account loss threshold is hit, close only positions that are currently losing. Stops the bleeding while keeping winners open.
