Finite Grid Trading with Equal-Cash Buys and Equal-Share Sells

Article FMZ forum · Author: Zero
Read the original

Summary

The article presents a stock grid method that divides a chosen price interval into a finite number of levels. As price falls, the trader divides remaining cash among lower grid levels; as price rises, remaining shares are divided among upper levels. It discusses how this equal-cash, equal-share approach differs from other allocation shapes, and gives practical guidance on choosing a security, estimating the range, setting grid spacing, establishing an initial position, following trade levels, and periodically adjusting the range. It also describes combining grids across stocks with differing activity and correlations.

The author offers personal trading experience and a historical simulation, including an example with a hypothetical sharp decline, but provides no systematic data set or independent validation. The article acknowledges that outcomes depend on the actual price path, range selection, and execution assumptions. Prices outside the chosen interval, prolonged trends, and limited capital can challenge the method; its claim of repeated profitable trades within the range does not guarantee an overall profit.

Key ideas

  • The equal-cash, equal-share grid allocates remaining cash across lower levels and remaining shares across higher levels.
  • A finite trading range and grid count determine the allocation schedule and constrain where the method operates.
  • The author recommends considering security activity, valuation or technical reference points, initial positioning, and disciplined execution.
  • The article compares several allocation shapes and suggests matching them to the expected range and holding horizon.
  • The author reports personal experience and a historical simulation, but the material is not systematic independent evidence.
  • Grid results depend on price path, range choices, available capital, and what happens when price leaves the range.
