aml_score_data: Function to score new data and predict change for each single currency pair

Description

Function is using the latest data from the financial assets indicator pattern and deep learning model. Prediction is a price change in the future for that asset will be used by the trading system

Usage

aml_score_data(
  symbol,
  num_bars,
  timeframe,
  path_model,
  path_data,
  path_sbxm,
  path_sbxs
)

Arguments

symbol

Character symbol of the asset for which the model shall predict

num_bars

Number of bars used to detect pattern

timeframe

Data timeframe e.g. 1 min

path_model

Path where the models are be stored

path_data

Path where the aggregated historical data is stored, if exists in rds format

path_sbxm

Path to the sandbox where file with predicted price should be written (master terminal)

path_sbxs

Path to the sandbox where file with predicted price should be written (slave terminal)

Value

Function is writing file into Decision Support System folder, mainly file with price change prediction in pips

Details

Performs fresh data reading from the rds file
