How to create algo strategy to automatically trigger reversal trades when a stock moves a certain %?
This can be used as base for 52 Week HL Strategy and as a base for any breakout trade as well.
But in this episode, we will be focussing on triggering reversal trades when a stock moves by 3%. So if a stock moves up by 3%, we will short it and viceversa. This is a simple mean reversion strategy.
So going into the script, the first thing we will do is store stock’s daily open and closing price into a variable.
price_close = close
price_open = open
Now we can then perform a calculation to determine the percentage price change.
price_change = price_close / price_open
The price_change variable now holds the calculation. So for example, if a stock opened at 100 and rallied 3% to close at 103, the price_change variable would be 103/100 which is 1.03.
But if the same stock opened at 100, and declined 3% to close at 97, the variable would read 97/100 which is 0.97.
As per the strategy, we already know that if a stock declined 3% or more, the price_change variable would be 0.97 or less, and we want to go long as we are trading reversal.
So let’s write the code for taking the trades now.
if price_change < 0.97
strategy.entry(“long”, strategy.long, 100)
And the code to go short if a stock rallies more than 3%.
if price_change > 1.03
strategy.entry(“short”, strategy.short, 100)
Lastly, we will plot the price_change variable in the data window to see and we can confirm that the trades are being executed.
plot(price_change)
And here are the results of our strategy.
This can be used as base for 52 Week HL Strategy and as a base for any breakout trade as well.
