Smart idea short term and if your brave, here is that old system I flock here now and then.
This is from my trading Buddy. You have seen this all before and I have posted these trades many times before. Its just following the Day Chart HA candles and now he's selling. You choose to either Buy or Sell and close at change of colour or cross over of the 5EMA +3.
It is Sell and take profit every 60 pips (depends on pair). Re-enter. On a pullback, Sell limit order 1.2 times larger every 60 pips up to 5 trades. Exit is average price plus 60 pips.
I use this Average price system in two of my EA's I have running. My challenge is to get the EA to change from Buy to Sell which is very hard. I have got it to work fully automatic but there is no way I can trade this big. I have to trade at a very small trade size and I still risk a $800 draw down.
It is of course a grid system where in this case, he is probably using a points gap of 0.5 ADR100.
