Grid King EA takes a new approach to grid trading.  The main focus when developing the EA was safety, by eliminating the margin-call risk which is usually associated with most grid systems on the market.  It also strives to achieve much higher returns than the average grid system, by spreading risk amongst multiple pairs and strategies which all have a limited effect on the account-equity.
The EA has been stress-tested for a period of 18 years and passes all those years succesfully without any high drawdown. (*Please use recommended accountsize guidelines -> see below)

The EA is also already optimized for 15 pairs, and more will follow in the future.  In theory, any pair or market can be optimized for the algorithm.
The EA uses a unique Spread Equalizer Algorithm (S.E.A.), which dramatically decreases the impact of spread and slippage on the stability.

At the moment, 2 strategies are used for entry:

  • “Volatility breakout” strategy, where the EA will trade in the direction of strong price movements.
  • “Return to Mean” strategy, where the EA will exploit the fact that price always returns to the mean.

Key Characteristics:

  • very stable growth curve as result of smart averaging techniques
  • “safety first” approach in development
  • optimizable for any market
  • ONLY grid-system on the market that passes 18 years of stress-tests on historical data on multiple pairs
  • fully automatic
  • Not sensitive to spread, commission, or account type, but ofcourse a low spread ECN broker will always work better and is recommended!
  • On-Chart visualisation of TP zones
  • You can use the same magic numbers on different pairs.  But the 2 different strategies must use 2 different magicnumbers
  • One of a kind S.E.A. (Spread Equalizer Algorithm), which greatly improves stability for bigger spreads and slippages

  • Enable autosettings and run only the optimized pairs
  • run only on H1 timeframe
  • Run only 1 chart for each pair (the EA will run both strategies from 1 chart)
  • Use leverage of 1:300 or bigger.  The EA will need enough free margin from time to time, so a high leverage is necessary.
  • works on all brokers (non FIFO only for now)
  • All account types are ok (standard, ECN, STP, Micro)
  • As with any EA, it is recommended you run it first on a demo account to get to know the trading style of the EA
  • Recommended to run on accounts nominated in EUR or USD for best performance of AutoSafety feature.

Accountsize Recommendations

  • balance > 200$ but < 2000$ -> use cent account!
  • balance >= 2000$ (or 200$ Cent) -> run max 2-3 pairs
  • balance >= 3000$ (or 300$ Cent) -> run max 3-4 pairs
  • balance >= 4000$ (or 400$ Cent) -> run max 4-5 pairs
  • balance >= 5000$ (or 500$ Cent) -> run max 8 pairs
  • balance >= 7500$ (or 750$ Cent) -> run max 10 pairs
  • balance >= 10000$ (or 1000$ Cent) -> run all pairs
  • It is only advised to run “Aggressive” or “Very Aggressive” mode when using only very few pairs (1-3)
  • When running all pairs, “Very Conservative” or “Conservative” mode is advised
  • Recommendation: the more pairs you run, the lower your risk setting should be.  You do NOT need aggressive risk setting to make nice profits!

How to run backtests

  • Use tickdata 99.90 for most accurate testing
  • use fixed spread or variable spread
  • Choose H1 timeframe
  • Choose period (for example 2007-2018)
  • Use default parameters, or set risk settings to your taste.
  • Use EUR or USD as account currency in tests
  • When using Tickdata 99.90% -> use GMT=2 or 3
