LCF Theta Vector

LCF Theta Vector is based on custom variation of RSI indicator in assistance of vector algorithm and built-in AUTO_OPTIMIZER module that allows for dynamic adaptation to current market conditions (no calibration needed) - the specific result is chosen on the basis of several different coefficients. All additional stoploss mechanics can be used together.

EA can be run on different symbols and timeframes but for reducing demand on computing power internal parameters are narrowed and it is highly recommended to run it on this symbols and timeframes:

  • XAUUSD (GOLD) at H1 time-frame (average 15 trades per month)
  • XAGUSD (SILVER) at H1 time-frame (average 8 trades per month)
  • USDJPY at H1 time-frame (average 21 trades per month)
  • and more in future

Default parameters are dedicated for XAUUSD (GOLD) symbol on H1 time-frame.

Implemented Modules

  • AUTO_OPTIMIZER - takes a piece of the market, then it makes from hundreds to even thousands of simulations with various parameters combinations, results are being further calculated and best result is applied for next period. For each symbol which is susceptible to used method, usable variants are narrowed to increase work speed and prevent from price anomalies. Some variants must be excluded for some symbols, becouse even if they have good results in simulation they don't have good performance in next period of time.
  • AUTO_LOT - auto-calculation of LOT value based on SL, BASE2ACC_RATIO and RISK values according to actual account balance. In most cases EA automatically obtain or calculate BASE2ACC_RATIO value. Otherwise it returns alert and value should be inserted manually (exchange ratio between margin and account currencies).
  • DTSL - (Differential Trailing Stop Loss) hybrid mechanism of trailing stoploss and takeprofit. DTSL_POINTS value determines hidden take profit level and the closer the price is to this level, the tighter it becomes the stoploss. Check comments section to see graphic explanation.


  • Recommended initial capital 1000+ USD (if minimum LOT=0.01) and 10000+ USD (if minimum LOT=0.1)
  • In some cases patience of the user (on XAGUSD there is average 8 trades per month)


  • STOP_LOSS - if true, use classic stop loss (required to enable additional stoploss mechanics).
  • SL_BREAKEVEN - if true, use standard break-even mechanic (according to SL_POINTS value).
  • TRAILING_SL - if true, use standard trailing stop loss mechanic (accoirding to TSL_POINTS value).
  • DTSL - if true, use DTSL mechanics (according to DTSL_POINTS value).
  • SL_POINTS - initial stop loss value in points.
  • TSL_POINTS - trailing stop loss value in points.
  • DTSL_POINTS - DTSL take profit value in points.
  • AUTO_LOT - if true, use AUTO_LOT module.
  • RISK - maximum risk per trade in percentage of current account balance (recommended range: 1-3).
  • BASE2ACC_RATIO - exchange rate between "margin_currency" from symbol specification and account currency (margin/account).
  • MAGIC_BUY - unique number for buy orders.
  • MAGIC_SELL - unique number for sell orders.
  • LOT - fixed LOT value (if AUTO_LOT=false).
  • LVL - max number of subsequent orders (separately for buy and sell, recommended range: 5-15).

Great backtests with strict conditions on slippages, commissions and spreads, will begin forward testing and update with performance.

Update 2018/01/26: Past 2 weeks with profitable trades on a real account and high resemblance to backtests.

Update 2018/02/12: Still in profit, some differences among traders, support is scarce. Still no live signal.

Update 2018/02/25: Positive trades for XAU and JPY so still in profit. Current support is null.

Update 2018/03/12: More profits mounting on real, still nothing is heard from author.

jpy and gold now good trades, but only 3* because 0 support
