Be clear on what ships here. The mod atr trailing stop indicator computes an average true range over fourteen bars and plots it as one line in a pane. There is no stop level, no ratcheting and no trailing logic anywhere in the source. What you get is the volatility reading a trailing stop would be built from.
This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

How the Mod ATR Trailing Stop Indicator calculates its values
True range per bar
Three distances compete. High to low, high to the previous close, and low to that close. Whichever is largest is the true range for that bar.
A simple average
`Period` `14` bars get added and divided. That is a plain mean rather than the Wilder smoothing the original method uses, so it reacts a little differently.
What is missing
No stop gets placed. A trailing stop would multiply this reading and ratchet a level against price. That second half does not exist in this file.
How to read the signals
The line measures size, never direction.
A rising reading means bars are growing.
Values read in price units rather than pips.
This is the number a stop distance would multiply.
Heights across two symbols mean nothing.
A quiet session drags the line toward zero.
Alert channels in this build: popup, push notification, email and sound, one message per closed bar.
`EnableAlerts` decides whether this tool speaks at all, and it ships on beside `EnablePopup`. Three further routes stay dark: `EnablePushNotify` forwards to your phone, `EnableEmail` mails out, and `EnableSound` sounds whatever `SoundFile` names.

Settings that fit your chart
A range reading behaves alike on any liquid market. EURUSD H1 is the reference chart, where fourteen bars spans most of a session. Drop to M5 and the line jumps at each open. Move up to daily and it tracks a fortnight.
When the Mod ATR Trailing Stop Indicator fails
The name promises a stop the source does not build.
A plain mean differs from Wilder’s smoothing.
The reading says nothing about direction.
One large bar lifts it for fourteen bars.

FAQ
Does this draw a trailing stop level?
No. The source computes an average true range and plots it, nothing more. A trailing stop needs a multiplier and a level that ratchets against price, and neither of those appears anywhere in the file.
How does Period 14 average the range?
As a plain mean of the last fourteen true ranges. Wilder’s original method smooths them instead, which weights recent bars more heavily, so this reading moves a little differently from a standard ATR.
What is the ATR plot useful for then?
Sizing. It is the number you would multiply to set a stop distance or to judge whether a move is large for current conditions, which is the same job it does inside any volatility-based tool.
Can the ATR plot ever fall below zero?
No. True range is a distance, and all three of its candidate measurements are absolute values, so the largest is always positive and a mean of positives cannot drop under zero.
Are results guaranteed?
No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Mod ATR Trailing Stop Indicator as one input. Always backtest before trading live.
