Hi Danbhai,
As you have said adds are very important to any system rather than bulk entry, but what I usually do is, if my two systems give entry signal on the same time, I go in with all the lots at once, instead of making adds. This has back fired sometimes, but the rewards are believe me extremely awesome. If it back fires I will only be a little upset because its like getting my two trades stopped out at the same day and has happened many times before
. But If SL is not hit and market moves in my direction, then I make partial exits with TSL, if the market is extremely bullish or bearish, this is very useful and extremely rewarding, I will be able to gain around 9R that day, if its not extremely bullish or bearish anyway TSL will be taken out because I keep a wider range for TSL getting triggered. Usually, adds are best as per my humble opinion because as you have said they let us avoid the initial risk and increase the final reward and I guess any method should have adds within it and partial profit booking within it to get good returns in the long time, just my humble opinion.
I was ignoring adds and partial profiting in my initial strategy and It was even difficult to break even, now I have added a rule for taking adds which is like pyramiding style, If I take 10 lots initially then on first add signal I will add 5 lots and next add signal 3 lots and final add signal 2 lots. Even, after making add rule, I found that I was giving away profits to the market because of absence of rule for partial booking of profits in my system, So , now I exit as per TSL based on 15 min charts for 0.6X of my initialy X entries and TSL based on 30 min charts for 0.4X of my entries. This, I have done for only one week, so lots of refinement in queue
I also found out most of the times I guess market movement correctly, but my stops get taken out and market reverses, so I need to find a re entry rule which will work on all market conditions and timings. Working on this part very hard for past few days, still seeing the skies and no clue yet
