Everything in this strategy library, arranged by the problem you actually have. New members keep
asking where to begin, and the honest answer depends on which part is not working yet.
1. Start from the problem, not the strategy
2. What these are and are not
Every one of these is a shape to adapt, not a strategy to run. The numbers in all of them are
placeholders — chosen to be readable rather than to be optimal, and left visible so you can change
them.
That is deliberate. A strategy with hidden parameters is a strategy you cannot reason about, and a
strategy you cannot reason about is one you will abandon the first week it loses.
3. The order most people should actually go in
Read
the simplest complete one first, even if you have written strategies before. It
takes four minutes and it establishes what "complete" means — an entry, a target, a stop and a time
exit. Most broken strategies are missing one of those four.
Then run
the baseline on your own data before you write anything of your own. Knowing
what a deliberately dumb rule earns on your recordings is the only way to tell later whether your
clever rule is actually clever.
After that, work on exits rather than entries. Everyone tunes entries; the difference between two
exits on the same entry is usually larger than the difference between two entries.
4. What none of them can do for you
None of them price your fills. Every strategy here shows a target and a stop, and every one of them
is quietly assuming you can transact at the price you see — which is not true, and the size of the
gap decides whether any of this works.
We measured it: a $5,000 market order in a $5–20 stock pays about 38 basis points one way, roughly
0.75% round trip (
what day trading a US stock really costs). One tick of slippage
removed 44% of the edge on a real model
(
one tick of slippage erased 44% of the backtest edge).
Read those two before you trust any backtest, including ours.
5. Then test on your own recordings
Not on ours, and not on resampled bars. The whole point of recording your own market is that the
backtest fills are the fills you would have had —
how to backtest a day trading strategy on US stocks walks through it, and the
day trading indicators and factors reference defines every factor these strategies
use.
