The entry for the tenkan sen/kijun sen cross is very straightforward - an order is placed in the direction of the cross once the cross has been solidified by a close. Nevertheless, in accordance with good trading practices, the trader should in mind any significant levels of near the cross and consider getting a close above those levels before executing their order.
The exit from a tenkan sen/kijun sen cross will vary with the particular circumstances of the chart. The most traditional exit signal is a tenkan sen/kijun sen cross in the opposite direction of your trade. However, personal risk management and time frame concerns may dictate an earlier exit, or an exit based upon other signals, just as in any other trade.
The tenkan sen/kijun sen strategy does not dictate use of any particular structure for stop-loss placement, like some other strategies do. Instead, the trader should consider their execution time frame and their money management rules and then look for the appropriate prevailing structure for setting their stop-loss.
