Trading of “SimpleCoreRanger standard"

Determining the Grid Range

From the current candlesticks, we will develop a trading strategy based on the highest and lowest prices of the past[PricePeriod] month.

About Trading
  • All trades are done on market orders. We do not place any limit orders
    • This made it possible to suppress trading when Spread expanded.
  • Since it is a grid trade, we do not set a stop loss
  • Trading is broadly divided into inside and outside the core range.
  • Within the Core Range, both short and long trades are traded
    • Above the Core Range, only short trades are taken
    • Under the Core Range, we only do long trades
    • The upper and lower limits of the core range are coreHeight and coreLowest, respectively.
Take Profit for each position and trade interval

There is one position in the same direction for each interval.

* For the calculation formula of INTERBAL, please see the original page.

Backtesting with AUDNZD

  • Account: NZX Zero (ECN) (NOZAX)
  • Initial Balance: $10,000
  • Currency Pair: AUDNZD #
  • Lot : 0.01 Lot
  • Parameters: values optimized on the aforementioned author’s PC
  • Period: January 1, 2013 ~ November 30, 2022

Although this EA is a grid trading system, it seems to be in the category of fairly small unrealized losses (Equity Drawdown Maximal). You can see the superiority of the idea (logic) of the Core Range.

But profitability is not very high. Therefore, we want to balance the tolerance for unrealized losses with the trading volume to increase the number of lots. A 0.01 lot operation could still have an unrealized loss of just over $1,000 during a 10-year backtesting period. When operating, please be aware of this before deciding the number of lots.

Also, please read the guidelines for optimization (the range of numerical values of parameters) on the author’s page.
