Scalping method using Stochastics 15 minute time frame

I have been scalping multiple pairs using Stochastic I trade 6:00 am Uk time until 10 am
I use the Stochastic with levels of 20 ,30 ,70 and 80 levels
The idea is to wait for the red and blue Stochastic lines to move below the 20 level and then take a trade
when the blue line crosses back through the 30 level a buy trade is activated
For a sell just do the opposite wait until red and line pass up through the 80 level
The sell trade is then activated when the blue line passes back through the 70 level
Normally on all pairs stop loss is taken to break even after 10 pips
I have back tested on Euro/Usd ,£/usd ,£/yen and euro/yen with 80 to 90 % success rate
Stochastic set to 8,3,3
I will post a couple of trades tomorrow

Just a couple of more trades taken on Friday 1st Euro /Yen 2nd £/Usd Trades are taken on red vertical line
Normally the stop loss is 20 pips and this stop loss is taken to break even after 10 pips Take profit is at users discretion
But normally 10 pips plus

Ok too late to take these trades all for ten pips and could have got out with 20 pips on £ yen
