This Expert Advisor requires the compiled indicator file TEMA_CUSTOM.ex5 in order to run. Place it to <terminal_data_folder>\MQL5\Indicators.
Note that the TradeAlgorithms.mqh library file allows using Expert Advisors with brokers who offer nonzero spread and the option of setting Stop Loss and Take Profit together with position opening. You can download more variants of the library at the following link: Trade Algorithms.
