Trading Strategy Practice Lab
Fifteen dedicated rule checkers and strategy simulations with fictional inputs and visual feedback.
Choose a strategy, review the fictional inputs, and change one assumption. Individual conditions explain whether the entered example passes, fails, or remains unresolved. No account or broker connection is required.
These tools check supplied values; they do not independently verify a chart, live data, news, or broker eligibility. Reviews default to unresolved where independent information is needed. Lists are oldest first, comma/space separated, with no thousands separators. Entries reset on reload and are not saved to an account.
01. RSI recovery rule checker
Wait for an oversold reading to recover while a defined trend and support test remain intact.
Read the exact conditions for this exercise
- Daily completed bars: close above SMA50 and SMA50 above its value five sessions earlier.
- Previous RSI14 below 30; current RSI14 at least 30.
- Current low tests a premarked support zone within 0.25 ATR14; close above prior close and support.
- Completed volume at least the mean of the preceding 20 completed daily volumes.
- Model a next-session entry only if its price remains above the planned stop and below the target.
Prices and indicators use the completed-bar and session conventions in the full guide. The ATR trail tool demonstrates protective-stop sequence only, not the full SMA200 exit simulation.
02. Breakout and volume checker
Test a completed close above a resistance level fixed before the breakout bar.
Read the exact conditions for this exercise
- Daily close above a resistance line tested on two distinct earlier sessions separated by at least three sessions.
- Prior close at or below resistance; current close above resistance and above SMA50.
- Completed volume divided by mean volume of preceding 20 sessions at least 1.5.
- No scheduled earnings inside the next five trading sessions; unknown calendar information remains unresolved.
- Model next-session entry, with entry no more than 0.5 ATR14 above resistance.

03. Pullback confirmation checker
Test a pullback to SMA20 inside a predefined rising daily trend.
Read the exact conditions for this exercise
- Daily SMA20 above SMA50; both above their values five completed sessions earlier.
- Current low within 0.25 ATR14 of SMA20; close above SMA20.
- Confirmation close above previous session high.
- Close above the premarked higher-low invalidation level; that level is fixed before confirmation.
- Consider next-session entry only when a premarked prior-high target remains above entry.

04. ATR trailing-stop simulator
Define a long-term trend state and update a one-way trailing reference after each completed session.
Read the exact conditions for this exercise
- Daily SMA50 above SMA200 and above its own value five sessions earlier.
- Completed close above both SMA50 and SMA200.
- A flat paper position may enter on the next session under this state; this is a state entry, not necessarily a fresh crossover.
- Initial modeled stop equals entry minus two times the last completed ATR14.
- Record no-flow share quantity, charges, and all event checks before a proposed entry.

- Current close above both current averages.
- MACD histogram positive using the same completed daily bars and 12/26/9 settings.
- Model next-session entry; initial stop equals entry minus 1.5 ATR14.

- Use completed five-minute regular-session bars after 09:45 and no later than 14:30 New York time.
- Pre-reclaim close at or below its corresponding session VWAP; reclaim close above its own VWAP.
- A later retest low within 0.1 of the retest-bar ATR14 of retest VWAP.
- Retest close above retest VWAP and above retest open; both bars must be from the same session.
- Reclaim volume at least the mean of the preceding five completed five-minute bars; model entry after retest completion.

09. VWAP rejection and short-risk checker
Study a bearish failed reclaim with short-side execution assumptions made explicit.
Read the exact conditions for this exercise
- Completed five-minute bars after 09:45 and no later than 14:30 New York time; same regular session.
- Prior close below prior session VWAP.
- Current high at least current VWAP and at most VWAP plus 0.1 ATR14.
- Current close below current VWAP, below current open, and below prior close.

- Absolute SMA20 change over five sessions divided by current ATR14 at most 0.5.
- Prior close below prior lower band; current close back above current lower band but below current middle band.
