In the first phase, an optimized deep predictive coding network (DPCN) based on a meta-heuristic reptile search algorithm (RSA) inspired by the intelligent hunting activities of the crocodiles is exploited to develop this RSA-DPCN predictive model. The proposed model has been compared with optimized versions of extreme learning machine (ELM) and functional link artificial neural network (FLANN) with genetic algorithm (GA), particle swarm optimization (PSO), and differential evolution (DE) along with the RSA optimizers. The performance of this model has been evaluated and validated through several statistical tests. In the second phase, the up and down trends are analyzed using the Higher Highs Higher Lows, and Lower Highs Lower Lows (HHs\/HLs and LHs\/LLs) trend analysis tool. Further, the observed trends are compared with the actual trends observed on the exchange price of real datasets. This study shows that the proposed RSA-DPCN model accurately predicts the exchange price. At the same time, it provides a well-structured platform to discern the directions of the market trends and thereby guides in finding the entry and exit points of the Forex market.<\/jats:p>","DOI":"10.3390\/axioms11080396","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T21:15:05Z","timestamp":1660252505000},"page":"396","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Novel Algorithmic Forex Trade and Trend Analysis Framework Based on Deep Predictive Coding Network Optimized with Reptile Search Algorithm"],"prefix":"10.3390","volume":"11","author":[{"given":"Swaty","family":"Dash","sequence":"first","affiliation":[{"name":"Department of Information Technology, Veer Surendra Sai University of Technology Burla, Sambalpur 768018, Odisha, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pradip Kumar","family":"Sahu","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Veer Surendra Sai University of Technology Burla, Sambalpur 768018, Odisha, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Debahuti","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Siksha \u2018O\u2019 Anusandhan (Deemed to be) University, Bhubaneswar 751030, Odisha, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pradeep Kumar","family":"Mallick","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Kalinga Institute of Industrial Technology (KIIIT), Deemed to be University, Bhubaneswar 751024, Odisha, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4837-5883","authenticated-orcid":false,"given":"Bharti","family":"Sharma","sequence":"additional","affiliation":[{"name":"School of Computing, DIT University, Dehradun 248009, Uttarakhand, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7491-8656","authenticated-orcid":false,"given":"Mikhail","family":"Zymbler","sequence":"additional","affiliation":[{"name":"Department of Computer Science, South Ural State University, 454080 Chelyabinsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3949-0302","authenticated-orcid":false,"given":"Sachin","family":"Kumar","sequence":"additional","affiliation":[{"name":"Big Data and Machine Learning Lab, South Ural State University, 454080 Chelyabinsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","first-page":"345","article-title":"A hybridized ELM-Jaya forecasting model for currency exchange prediction","volume":"32","author":"Das","year":"2020","journal-title":"J.
