The investment strategy of Livermore, who once fought against J.P. Morgan:
First buy 20% as the base position,
If you buy it wrong,
Stop loss immediately when it drops 10%,
The loss amount is 2% of the total position.
If you buy it right, add 20% immediately for every 10% increase,
The last time you add 40%,
As long as it does not fall below 10%,
Hold it,
Once it falls below 10%,
Immediately sell all positions.
