Indicator Rules (Consistent Across All Versions):
- Loss Amount = ATR Multiplier multiplied by the Simple Moving Average (SMA) of the True Range over the specified InpATRLength bars.
- The stop level moves upwards towards the price as long as the price remains above it. Conversely, it moves downwards towards the price when the price is below it.
- The stop level reverses its position to the opposite side, and an arrow is displayed, when the price closes beyond the current stop level.
Translation Notes: Pine Script to MQL5/Python
- ta.tr(true): For the initial bar, where there is no preceding close price, the true range is calculated as the difference between the high and low prices.
- ta.sma(x, n): The SMA remains undefined (na) until at least 'n' bars have formed. The first valid value appears at bar n-1.
- nz(stop[1], src): This refers to the previous stop level. If the previous stop level is undefined (na), the current price (src) is used instead.
- var float stop = na: This variable retains its state from one bar to the next. In MQL5, this is translated to a persistent buffer, and in Python, it is managed as a running array.
- ta.crossover / ta.crossunder: These functions evaluate to strictly false when either of the input conditions is undefined (na). This is particularly relevant for the first valid bar calculation.
Repository: github.com/RAo797bit/pine-python-mql5-conversion. This repository includes the Pine Script source, a Python port with a detailed bar-by-bar reference implementation for verification, and a parity test to compare the MQL5 output against both the Pine Script and Python versions.
The indicator compiles cleanly in MetaEditor with zero errors and zero warnings.
