1. What These Strategies Are

This guide covers the four strategies in the GFPB family: GFPB, GFPB Precision, Tuesday Special, and Thursday Special. All four are built on the same underlying GFB template, so the property panels look almost identical at a glance. Each one differs in a small number of fields that change which day it trades, how its TPs and stop are set, and (in two cases) how it processes price data.

Use this guide to keep the four straight: what is the same across all of them, and the specific fields you should not change between strategies.

NOTE: GFPB is the entry signal that the rest of the lineup is built on. GFPB is what was previously known as “2.1C.” Tuesday Special is what was previously known as “2.2A.” Thursday Special and GFPB Precision are their own variants. Wherever a panel still says “GFP” or “GFB,” read it as GFPB — same product, older label.

NOTE: Please be aware that the contract sizes shown in this article reflect the default settings as currently coded. When setting them up on your own, pay close attention to avoid using the wrong instrument or an inappropriate contract size. See Contract Sizing for Vector Strategies: Prop Firm vs. Cash Accounts for full guidelines.

CRITICAL: Do not run GQZeroLimit alongside GFPB on the same trading account. Both products contain an active GFPB entry layer; running them together produces doubled exposure on the same signal.

2. Strategy Lineup at a Glance

The table below summarises the differences between the four strategies. Anything not listed here is either identical across all four or covered in the per-strategy reference further down.

NOTE: Calculate setting matters. Three of the four (GFPB, GFPB Precision, Thursday Special) run on each tick — they react intra-bar. Tuesday Special runs on bar close only — it evaluates once per 15-minute candle close. Do not change this between strategies; each is designed for the mode shown.

3. GFPB (a.k.a. 2.1C)

The base GFPB strategy. Trades Monday, Wednesday, and Friday in both directions. Two-position structure with TP1 at 50 points and TP2 at 80 points. Single shared stop at 125 points, with a Monday-only override that caps the stop to 75 points.

NOTE: Even though the buy/sell sub-toggles for Tuesday and Thursday show as ON in the panel, both day masters (Tuesday, Thursday) are OFF, so the strategy will not fire on those days. The day master is the deciding switch — sub-toggles only matter when the day master is ON.

4. GFPB Precision

A more conservative, filtered version of GFPB. Same days (Mon, Wed, Fri), same entry/TP/SL geometry, same Monday SL override. The difference is internal: GFPB Precision applies an additional set of filters and will skip a signal when the day’s conditions don’t look right for taking the position. The result is less frequent trades than GFPB on the same days, with a tighter quality bar.

NOTE: Use case. If you want a lower-frequency, more selective version of GFPB, run Precision. The settings panel is virtually identical to GFPB, so audit the configuration the same way — the filtering happens internally.

5. Tuesday Special (a.k.a. 2.2A)

Single-day strategy that runs Tuesday only. Same two-position structure as GFPB at 50 / 80 points, but the stop architecture is different: Tuesday Special uses a Stop Loss Filter (a points-based filter that blocks setups whose computed SL exceeds 90 points) plus a separate StopLoss Ratio block with a 125-point minimum. It also adds a Break Even rule that fires at 20 points. Unique among the four — it’s the only one that calculates on bar close.

NOTE: Tuesday Special’s Stop Loss Filter is unique to this strategy — the other three use a single Limit Points SL field. The filter is what gives Tuesday Special its more selective behaviour: by skipping wide-stop setups, it avoids the most exposed trades the day can produce.

6. Thursday Special

Single-day strategy that runs Thursday only. Different shape from the other three: a single position (Position2 is disabled with Qty = 0) running 2 contracts on Position1 at a 125-point TP, and a tight 50-point stop. Trailing Move SL is OFF on this strategy.

NOTE: Thursday Special is the odd one out. Single-position with 2 contracts at a 125 pt TP, a 50 pt stop, and no trailing/BE. Don’t copy the StopLoss Ratio (50) or Limit Points (50) values from this strategy into any of the others — they only make sense in Thursday Special’s configuration.

7. Common NinjaTrader Setup

The fields below sit at the bottom of every strategy panel in the family. Apart from Calculate (covered above) and Label, they are identical across all four strategies and should not be changed.

8. Cross-Strategy Notes

• Coverage. Run together, GFPB (or GFPB Precision) plus Tuesday Special and Thursday Special covers all five weekdays without overlap — that’s the design intent of the family.
• Don’t double up. Pick one of GFPB or GFPB Precision per account — running both at once on the same account doubles your Monday/Wednesday/Friday exposure on the same signal.
• Don’t mix with GQZeroLimit. GQZeroLimit pairs with the GFPB signal layer on its own — running it alongside any of these strategies on the same account doubles the entry exposure.
• Don’t change Calculate. Three of the four are tuned for On each tick; Tuesday Special is tuned for On bar close. Switching either way changes how signals fire.
• Don’t change Entries per direction. All four are designed for 1 entry per direction. Lowering or raising it breaks the intended behaviour.
