To run this script live, you need a data provider that offers on-chain L2 data (reserves, swap events). Recommended stack:
Python pseudo-code for the alert:
if fe_script.sushi_x_top(pair='ETH/WETH', chain='polygon') == True:
send_alert(f"🔴 Sushi X Top detected on pair. Short entry recommended.")
place_order(side='sell', type='limit', price=current_price * 0.98)
Automated market makers (AMMs) like SushiSwap rely on invariant formulas (x*y=k). However, financial expression (FE) scripts — small, domain-specific programs encoding trade conditions, slipptolerance cascades, or order dependencies — introduce a new layer: meta-execution.
Until now, no formal model has linked FE scripts to topological data analysis (Top), where trade order and liquidity depth form a simplicial complex. This paper addresses that gap.
In a traditional setup, you might manually keyframe a logo moving across the screen. In an FE Sushi setup, you write a single expression that drives: fe expression script sushi x top
This is the "roll"—tight, contained, and efficient. For example, a script like transform.position = [time*100, Math.sin(time)*50] simultaneously creates horizontal movement and a gentle undulation.
The FE boundary prevents a player from deleting a game wall or flying on their own accord because the server would simply overwrite those changes in the next update tick. However, animations are unique. The Roblox engine allows clients to play animations locally to ensure smooth movement without latency.
The Roblox platform utilizes a client-server architecture where the server acts as the authoritative source of truth for the game state. Historically, clients had the ability to make changes to their character that would automatically replicate to all other players. This led to significant security vulnerabilities, commonly referred to as "hacking." To mitigate this, Roblox enforced the "FilterEnabled" (FE) mode on all games.
Within this context, "FE Scripts"—often associated with custom expressions or cosmetic overrides—leverage local client permissions to modify the visual appearance of an avatar. While these modifications are strictly local unless validated by the server, they demonstrate the flexibility of the Roblox engine’s rendering pipeline. To run this script live, you need a
First, let’s break down the jargon. In quantitative analysis, an Expression Script is a lightweight piece of code (often using syntax similar to Pine Script, Python, or platform-specific DSLs) that allows you to write mathematical expressions directly against time-series data.
Unlike heavy object-oriented programming, Expression Scripts are designed for one-liner logic. They take inputs (price, volume, volatility) and output a signal.
Standard syntax example:
signal = crossover(close, ema(close, 20))
The FE (Financial Engineering) enhancement means we are not just using simple moving averages. We are using derived metrics: logarithmic returns, volatility cones, skewness, and liquidity depth. Python pseudo-code for the alert: if fe_script
Select your layer’s Position property. Hold Alt (Win) or Option (Mac) and click the stopwatch. Paste this:
// FE Sushi X Top - Cursor Follower with Float
x = thisComp.layer("Control Null").transform.position[0];
y = thisComp.layer("Control Null").transform.position[1];
oscY = Math.sin(time * 10) * 20;
[x, y + oscY];
What this does: It reads a "Control Null" layer’s position (The Top), then adds a sinusoidal (Sushi wave) oscillation of 20 pixels.
Great scripts don't break. Add try ... catch (err) value to your expressions. If the script fails (e.g., missing a layer), it simply defaults to the static value instead of showing a neon red error.
