Candlestick charts can interpret opening, high, low and closing values of an asset in a single visual. In addition to these advantages, the large number of candlestick chart patterns makes their practical use difficult. In the study developed forthis purpose, a software framework that uses candlestick charts and predicts the trend direction was created. The study consists of four stages. In the first step, a system that recognizes candle patterns is created. In the second stage, the performance of the model is measured by running training and testing processes on data sets in which candlestick chart types and trend direction are labeled. In the machine learning phase, community methods such as xgboost were used. In the last stage of the study, it was seen that with the strategy based on only recognizing the candlestick pattern and taking position in the direction of the trend based on proposed approach, higher profit was obtained in 11 world indices compared to Buy&Hold strategy.\u003Cbr>Cite this article as: Santur Y.

Investors and portfolio managers try to gain profits and minimize risks by taking positions in the right direction and at the right time. For this purpose, technical analysis is used to interpret price charts made up of time series [1] . It includes many tools such as technical analysis, moving averages, indicators and oscillators, statistical-based series and |  | pattern-based formations. Therefore, it is widely used by real investors and technical analysts, as well as algorithmic robots that perform autonomous transactions in crypto and stock markets [2] .\u003Cbr>In the trading, some of the earliest technical trading analysis was used to track prices of rice in the 18th century. Much of the credit for candlestick charting goes to Munehisa Homma, a rice merchant from Sakata, Japan |\n| *Corresponding author.\u003Cbr>*[E-mail address: ysantur@firat.edu.tr](E-mail address: ysantur@firat.edu.tr)\u003Cbr>This paper was recommended for publication in revised form by Regional Editor Ahmet Selim Dalkılıç |  |  |\n\nPublished by Yıldız Technical University Press, İstanbul, Turkey  \nCopyright 2021, Yıldız Technical University.

As shown in Fig. 1, they are formed by consolidating all price movements in a certain period, such as the hourly, daily, weekly in a single visual.
