There is no doubt that the strategy is simple and useful. Though RH's valid doubt was not answered, I suggest we may use 27 points level for top up. That is in case of buy, when price crosses 8 DEMA from below, buy one lot. When price crosses 8DEMA plus 27 points, add another lot. Please remember, as per strategy 8DEMA plus 27 points is also SL for short and therefore, in case of of buy, we may treat the range between 8DEMA and 8DEMA plus 27 points as high risk range and above 8DEMA plus 27 points as low risk range,. Target can continue at 8DEMA plus 70. Let me know views of others
