SMA 10, 20 and 30 bars turned up in the last 5 bars:
roc(sma(10), 5) > 0 and roc(sma(20), 5) > 0 and roc(sma(30), 5) > 0 and ref(roc(sma(10), 5), 5) < 0 and ref(roc(sma(20), 5), 5) < 0 and ref(roc(sma(30), 5), 5) < 0

RSI turning up after remaining below30 or flat or negative over last 3days:
rsi(14) > ref(rsi(14), 1) and (istrue(rsi(14) < 30, 3) or roc(rsi(14), 3) 1.2 * ref(hhv(high, 20), 10)

Stocks down 20% from their last 20-bar highest high, 10 days ago:
high < 0.8 * ref(hhv(high, 20), 10)

Horizontal resistance can be defined as the highest close value over N-bar
hhv(close, N)

The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
