Dow as analysed had reached 50Dema where 100points are in pocket. From here Dow can take support at 50 Dema. Booking 50% is good idea. Rest can be carried forward with trailing SL. Dow can come down to meet 20Dema if 50Dema is broken. Normally 50Dema is good support but 20Dema is below 50Dema which suggest a sell signal. This trade is very eassy as price has ran above sell segnal ie( 20Dema crossing below 50Dema ).
