Commander in Pips: Yes. The question is should we do that or not. This is not break your risk management rule and hold risk/profit ratio, but probability of exiting at the end with profit will become smaller. Still this is not forbidden, but demands more experience. We can treat it as a conservative approach – enter with 0.08 lot, aggressive approach to enter with 0.21 lot. Since we need to increase probability of profitable trade we will lock total position with 29$ profit and add just 0.08 lot. Pipruit: I agree.Chart #3 | EUR/USD 30-min Commander in Pips: Now is Entry #4 at 1.3260 by the same conservative approach. If you want you can make the same sophisticated calculations by yourself for aggressive approach. Pipruit: Ok, conservative will be: Moving stop at breakeven of Entry #3 at 1.3286. So Entry#1 and Entry#2 now locked in profit. Entry #4 conservative lot is $50/((1.3295-1.3260)*100,000) = 0.11 lot. Aggressive way: ((Entry#1 1.3365- Stop 1.3286)+(Entry #2 1.3328-Stop 1.3286)+$50)/((1.3295-1.3260)*100,000) = 0.38 lot or, for riskless position = ((Entry#1 1.3365- Stop 1.3286)+(Entry #2 1.3328-Stop 1.3286))/((1.3295-1.3260)*100,000) ~ 0.27 lot. Commander in Pips: Right. So, that’s all – market has hit the target of Butterfly by the end of trending day at 1.3195. What is profit? Pipruit: Let’s see: 1.Conservative approach: 0.1*(1.3365-1.3195)+0.1*(1.3328-1.3195)+0.08*(1.3286-1.3195)+0.11*(1.3260-1.3195) = $447.30 2. Average approach (holding riskless trade from entry #3): 0.1*(1.3365-1.3195)+0.1*(1.3328-1.3195)+0.13*(1.3286-1.3195)+0.27*(1.3260-1.3195) = $596.80 3. Aggressive approach (risk holds constant at $50): 0.1*(1.3365-1.3195)+0.1*(1.3328-1.3195)+0.21*(1.3286-1.3195)+0.38*(1.3260-1.3195) = $741.10 Commander in Pips: Yep. That’s it. And what about profit without scaling in? Pipruit: Oh, yes: 0.1*(1.3365-1.3195) = $170. Commander in Pips: So, the choice is up to you – apply scaling or not. Before this chapter you did not want to do it… Pipruit: Well, now I see that this is quite useful tool. Although I still need some time to adopt it into my trading system. But I understand the major idea of scaling. While you scale in or out – money management has to be accomplished; probability of profit has to become higher; context for trading has to hold. Commander in Pips: Right. Also when you are scaling in – don’t forget to control the margin. P.S.
