Thesis
Catch sustained moves by going long when the fast EMA crosses above the slow EMA.
Fits Trend following setups — works best when the underlying market behavior matches the thesis, and breaks down when it doesn't. Pair with the backtester's walk-forward mode before committing real capital.
Long flat periods broken by sharp upward jumps when a sustained trend lines up — and visible drawdowns during ranging markets when the cross fires both ways inside a few bars.

Indicators
ema_fastEMA (period 12)Exponential moving average over the last 12 closes — a short-term smoother that reacts quickly to new prints.
ema_slowEMA (period 26)Exponential moving average over the last 26 closes — a slower baseline that captures the broader regime.
Entry conditions
The bot opens a position the bar after every condition below has fired.
- Enter long the bar after EMA(12) crosses above EMA(26).
- Cooldown of 2 bars after an exit prevents instant whipsaw re-entries.
Exit conditions
Any of the conditions below will close the position.
- Close on the down-cross: EMA(12) back below EMA(26).
- Trailing stop of 4% locks in profits if the cross reverses without a clean down-cross.
Expected behavior
Long flat periods broken by sharp upward jumps when a sustained trend lines up — and visible drawdowns during ranging markets when the cross fires both ways inside a few bars.
Equity-curve character, not a return forecast. Backtests are not promises about live performance.
