Coming from EasyLanguage

A real import, the ideas side by side, and the names that translate.

This is a real run of the importer on a small EasyLanguage script. The result compiles. 6 lines were read: 3 carried over exactly, 3 were adapted and 1 came back as decisions for you.

What you paste · EasyLanguage

Inputs: FastLen(20), SlowLen(50);
Variables: FastAvg(0), SlowAvg(0);
FastAvg = XAverage(Close, FastLen);
SlowAvg = XAverage(Close, SlowLen);
If FastAvg crosses over SlowAvg then Buy next bar at market;
If FastAvg crosses under SlowAvg then Sell next bar at market;

Line by line

Status	Your line	What happened
Exact	`FastAvg = XAverage ( Close , FastLen ) ;`	a calculation carried over
Exact	`SlowAvg = XAverage ( Close , SlowLen ) ;`	a calculation carried over
Exact	`Buy next bar at market ;`	an order at market carried over
Adapted	`If FastAvg crosses over SlowAvg then Buy next bar at market ;`	a condition that places orders became a rule
Adapted	`Sell next bar at market ;`	sell closed the open position, which became close_all on that side
Adapted	`If FastAvg crosses under SlowAvg then Sell next bar at market ;`	a condition that places orders became a rule
Your call	`the script header`	EasyLanguage carries no market or bar size, so EURUSD on 1h was filled in: set the ones you want

How the ideas translate

In EasyLanguage	In AlgoBarsX
`Inputs: FastLen(20);`	input FastLen = 20
`Variables: FastAvg(0);`	state FastAvg = 0
`XAverage(Close, FastLen)`	ema(close, FastLen)
`Average, WAverage`	sma, wma
`If a crosses over b then …`	when crosses_above(a, b):
`Buy next bar at market;`	buy. Market orders already fill at the next bar's open.
`Sell next bar at market;`	close_all side: long
`CurrentBar`	bar.index

Tip. EasyLanguage variables become state values. Where one is simply recalculated every bar, you can delete the state line and keep the assignment.
